Hint:Here in this question we have to find the value of 2 power 100. So first we write the number in the form of exponent and then using of laws of indices and tables of multiplication write the number as . Then on multiplying the number 2 10 times by itself and the obtained result by itself another 10 times we obtain the result.
Complete step by step answer:
The exponential number is defined as the number of times the number is multiplied by itself. It is represented as , where is the numeral and represents the number of times the number is multiplied. Now we consider the given question. The number raised to the power of . Usually, the power term is written like a superscript of the given number. For example, if we have a number is raised to the power of . This can be written as , here is the power so we have written it as a superscript of .Therefore, the number raised to the power of is written as . We solve this question by two methods.
Method 1: In this method we are going to solve this problem by considering the logarithmic function. Consider,
On applying the log on both sides we get
By the laws of logarithmic functions , the above inequality is written as
The , on substituting the value in above inequality we have
On multiplying 100 and 0.69315 we get
Taking antilog on both sides we get
On simplifying we get
Method 2: Consider
By the tables of multiplication, the number 100 can be written as a product of 10 and 10.
By the laws of indices, we have , the above term can be written as
First, we simplify the term which is present in the bracket. When 2 is multiplied 10 times by itself we get the product as 1024. Therefore, we have
The number 1024 has the power 10. So the number 1024 is multiplied 10 times by itself. When the number is multiplied by itself we get the product as
This is a huge number, this can be written in the scientific form. So we have
Hence the 2 raised to the power of the 100 is .
Note:The exponential number is defined as the number of times the number is multiplied by itself. It is represented as , where a is the numeral and n represents the number of times the number is multiplied. For the exponential numbers we have a law of indices and by applying it we can solve the given number. A huge number can be written in the scientific form.
