Exercise 6.3 of Squares and Square Roots is based on the following topics:

1. Finding square roots

The square root of a number is the inverse operation of squaring a number. The square of a number is the value acquired by multiplying it by itself, whereas the square root of a number is the factor of a number that produces the original number when multiplied by itself. If 'x' is the square root of 'y’, it means that x × x = y.

Note: Finding the square root of a perfect square number is simple. Positive numbers which can be expressed as the product of two numbers are known as perfect squares. Perfect squares are the positive numbers which can be expressed as the product of a number by itself. In simple words, Perfect squares are the numbers which can be expressed as the value of power 2 of any number.

2. Finding square root through repeated subtraction

In this method, we subtract the consecutive odd numbers from the number for which we want to find the square root, till we get the resultant value as 0. The number of times we subtract will be the square root value of the given number. This method is only applicable for perfect square numbers.

3. Finding square root through prime factorisation

Prime factorization of a number is to express that number as a product of prime factors. Steps to be followed to find the square root of a given number through the prime factorization method are:

  • Firstly, divide the given number into its prime factors.

  • Next, form pairs of similar factors in such a way that both factors in each pair are equal.

  • Take one factor from each pair.

  • Then, find the product of the factors that are obtained by taking one factor from each pair.

  • The product value is equal to the square root of the given number.

Exercise 6.3

1. What could be the possible ‘one’s digits of the square root of each of the following numbers?

i. $\text{9801}$

Ans: We know that the one’s digit of the square root of the number ending with  $1$ can be $1$ or $9$.

Thus, the possible one’s digit of the square root of $9801$ is either $1$ or $9$.


ii. $\text{99856}$

Ans: We know that the one’s digit of the square root of the number ending with  $6$ can be $6$ or $4$.

Thus, the possible one’s digit of the square root of $99856$ is either $6$ or $4$.


iii. $\text{998001}$

Ans: We know that the one’s digit of the square root of the number ending with  $1$ can be $1$ or $9$.

Thus, the possible one’s digit of the square root of $998001$ is either $1$ or $9$.


iv. $\text{657666025}$

Ans: We know that the one’s digit of the square root of the number ending with $5$ will be $5$.

Thus, the only possible one’s digit of the square root of $657666025$ is $5$.


2. Find the numbers which are surely not perfect squares without doing any calculations.

i. $\text{153}$

Ans: The perfect square of numbers may end with any one of the digits $0$, $1$, $4$, $5$, $6$, or $9$. Also, a perfect square has an even number of zeroes at the end of it, if any.

We can see that $153$ has its unit place digit as $3$.

Hence, $153$ cannot be a perfect square.


ii. $\text{257}$

Ans: The perfect square of numbers may end with any one of the digits $0$, $1$, $4$, $5$, $6$, or $9$. Also, a perfect square has an even number of zeroes at the end of it, if any.

We can see that $257$ has its unit place digit as $7$.

Hence, $257$ cannot be a perfect square.


iii. $\text{408}$

Ans: The perfect square of numbers may end with any one of the digits $0$, $1$, $4$, $5$, $6$, or $9$. Also, a perfect square has an even number of zeroes at the end of it, if any.

We can see that $408$ has its unit place digit as $8$.

Hence, $408$ cannot be a perfect square.


iv. $\text{441}$

Ans: The perfect square of numbers may end with any one of the digits $0$, $1$, $4$, $5$, $6$, or $9$. Also, a perfect square has an even number of zeroes at the end of it, if any.

We can see that $441$ has its unit place digit as $1$.

Hence, $441$ is a perfect square.


3. Find the square roots of $\text{100}$ and $\text{169}$ by the method of repeated subtraction.

Ans: It is already known to us that the sum of the first n odd natural numbers is n2.

For $\sqrt{100}$

  1. $100-1=99$

  2. $99-3=96$

  3. $96-5=91$

  4. $91-7=84$

  5. $84-9=75$

  6. $75-11=64$

  7. $64-13=51$

  8. $51-15=36$

  9. $36-17=19$

  10.  $19-19=0$

After subtracting successive odd numbers from $1$ to $100$ , we are getting a $0$ at the 10th step.

Hence, $\sqrt{100}=10$

For $\sqrt{169}$

  1. $169-1=168$

  2. $168-3=165$

  3. $165-5=160$

  4. $160-7=153$

  5. $153-9=144$

  6. $144-11=133$

  7. $133-13=120$

  8. $120-15=105$

  9. $105-17=88$

  10. $88-19=69$

  11.  $69-21=48$

  12.  $48-23=25$

  13.  $25-25=0$

After subtracting successive odd numbers from $1$ to $169$, we are getting a $0$ at the 13th step.

Hence, $\sqrt{169}=13$

Ans: According to the question, each student donated as many rupees as the number of students in the class.

We can find the number of students in the class by doing the square root of the total amount donated by the students of Class VIII.

The total amount donated by students is Rs. $2401$

Then, the number of students in the class will be $\sqrt{2401}$

$\sqrt{2401}=\sqrt{\underline{7\times 7}\times \underline{7\times 7}}$

$=7\times 7$

$=49$

Thus, there are total $49$ students in the class.


8. Around 2025 plants are to be planted in a garden in such a way that each row contains as many plants as the number of rows. Find the number of rows and the number of plants in each row.

Ans: According to the question, the plants are being planted in a garden in such a way that each row contains as many plants as the number of rows.

So, the number of rows will be equal to the number of plants in each row.

Hence,

The number of rows $\times $ Number of plants in each row $=$Total number of plants

The number of rows $\times $ Number of plants in each row $=$ $2025$

The number of rows $\times $ The number of rows $=$ $2025$

The number of rows $=$$\sqrt{2025}$

$\sqrt{2025}=\sqrt{\underline{5\times 5}\times \underline{3\times 3}\times \underline{3\times 3}}$

$=5\times 3\times 3$

$=45$

Thus, the number of rows $=45$ and the number of plants in each row $=45$.


9. Find the smallest square number that is divisible by each of the numbers $\text{4,9}$ and $\text{10}$.

Ans: We know that the number that is perfectly divisible by each one of $4,9$ and $10$ is their L.C.M

$=180$

It can be clearly seen that $5$ cannot be paired.

Therefore, we have to multiply $180$ by $5$ in order to get a perfect square.

Thus, the smallest square number divisible by $4,9$ and $10$$=180\times 5=900$


10. Find the smallest square number that is divisible by each of the numbers $\text{8,15}$ and $\text{20}$.

So, taking the L.C.M of these numbers 

$2$

$8,15,20$

$2$

$4,15,10$

$2$

$2,15,5$

$3$

$1,15,5$

$5$

$1,5,5$


$1,1,1$

L.C.M$=2\times 2\times 2\times 3\times 5$

$=120$

It can be clearly seen that the prime factors $2$, $3$ and $5$ cannot be paired.

Therefore, we have to multiply $120$ by $2$, $3$ and $5$ in order to get a perfect square.

Thus, the smallest square number divisible by $8, 15$ and $20$ is $120\times 2\times 3\times 5 = 3600$
