What is 20 to the Power of 81?

In order to solve for 20 to the power of 81, we must first understand the structure. The number 20 is called the base, and the number 81 is called the exponent. In short, the base must be multiplied by itself the number of times as the exponent. Let’s look at this problem in more detail.

Solution: 20 to the Power of 81 is equal to 2417851639229258349412352000000000000000000000000000000000000000000000000000000000000000000000000000000000

Methods

Step-by-step: finding 20 to the power of 81

The first step is to understand what it means when a number has an exponent. The “power” of a number indicates how many times the base would be multiplied by itself to reach the correct value.

The second step is to write the number in the base-exponent form, and lastly calculate what the final result would be. Consider the example of 2 to the power of 4: in exponent form that would be

242^4
. To solve this, we need to multiply the base, 2 by itself, 4 times -
2⋅2⋅2⋅22\cdot2\cdot2\cdot2
= 16. So
24=162^4 = 16
.

So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:

208120^{81}

To simplify this, all that is needed is to multiply it out:

20 x 20 x 20 x 20 x ... (for a total of 81 times) = 2417851639229258349412352000000000000000000000000000000000000000000000000000000000000000000000000000000000

Therefore, 20 to the power of 81 is 2417851639229258349412352000000000000000000000000000000000000000000000000000000000000000000000000000000000.
