So you would like to raise 21 to the power of 15? In this article you can find the answer below. Here we explain how to do the calculation to raise 21 to the 15 power. At the end we will show how to calculate 21 to the power of 15 using a scientific calculator.
First and foremost, let’s explain the calculation. When you are looking to calculate 21 raised to 15 you are conducting mathematical operation “exponentiation” where 21 is referred to as a “BASE” and 15 is called an “EXPONENT”. When you raise 21 to the power of 15 all you are doing is multiplying the base by itself as many times as exponent. So in our example you multiply 21 by 21 times x 15 . Using numbers this can be expressed as 21 15 or 21^ 15.
The answer to what is 21 to the power of 15?
21 to the power of 15 expressed as 21 15or 21^ 15 or 21 x … x 21 (15 times) = 6.8122318582952E+19
Again your answer is 6.8122318582952E+19.
