So you would like to raise 8 to the power of 21? In this article you can find the answer below. Here we explain how to do the calculation to raise 8 to the 21 power. At the end we will show how to calculate 8 to the power of 21 using a scientific calculator.
First and foremost, let’s explain the calculation. When you are looking to calculate 8 raised to 21 you are conducting mathematical operation “exponentiation” where 8 is referred to as a “BASE” and 21 is called an “EXPONENT”. When you raise 8 to the power of 21 all you are doing is multiplying the base by itself as many times as exponent. So in our example you multiply 8 by 8 times x 21 . Using numbers this can be expressed as 8 21 or 8^ 21.
The answer to what is 8 to the power of 21?
8 to the power of 21 expressed as 8 21or 8^ 21 or 8 x … x 8 (21 times) = 9.2233720368548E+18
Again your answer is 9.2233720368548E+18.
