FAQs on NCERT Solutions for Class 7 Maths Chapter 13 Exponents and Powers (EX 13.1) Exercise 13.1
1. What is Chapter 13 Exercise 13.1 of Class 7 Maths all about and what will students learn here?
Chapter 13 Exercise 13.1 of Class 7 Maths is Exponents and Powers and this exercise has the fundamental ideas related to exponents and powers. Students are going to learn the properties of exponents, associated formulas, scientific notations, the order of magnitude, and exponential laws along with other basic concepts through this chapter.
2. What is an exponent?
An exponent refers to the process of repeatedly multiplying the same number keeping in mind the total number of times.
Eg: 32 = 3 x 3
Thus, the use of exponents raises a given number to a certain power, wherein the exponent is called power. The number, which is raised to the power is known as the base.
Eg: in 32, 3 is base and 2 is the exponent.
3. How are exponents and powers dealt in Mathematics?
If A is any rational number with a non-zero value, and N is any natural number, then, A × A × A × A ×…..× A (N times) is considered to be A^N, where A is the base and N is the value of the exponent. Similarly, A^N is called the power and A^N is read as A to the power of N. This is how exponents and powers are dealt with in mathematics.
4. What is exponential notation?
Exponential notation is the process of the expression of large numbers as one number multiplied by 10 is raised to a power of any given exponent. Powers of exponential notations can be in either of the two forms.
Positive power denoting a large number
Negative power denoting a small number.
