Math Tutor Explains: What is 9 to the Power of 71?

A math tutor would explain that to solve for 9 to the power of 71, we must first understand the structure. The number 9 is called the base, and the number 71 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.

Math Tutor's Solution: 9 to the Power of 71 is equal to 56392087339601733413306017749077372989860250021295987473736382457209

Methods

Step-by-step from math tutor: finding 9 to the power of 71

The first step a math tutor would suggest 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:

9719^{71}

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

9 x 9 x 9 x 9 x ... (for a total of 71 times) = 56392087339601733413306017749077372989860250021295987473736382457209

Therefore, 9 to the power of 71 is 56392087339601733413306017749077372989860250021295987473736382457209.
