Math Tutor Explains: What is 99 to the Power of 86?

A math tutor would explain that to solve for 99 to the power of 86, we must first understand the structure. The number 99 is called the base, and the number 86 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: 99 to the Power of 86 is equal to 4213342221547683589715320328404409546857704031154349329931385998059963276851850573663720311246887790919404881692290237811708041831502416703427631350589356619026233196541401

Methods

Step-by-step from math tutor: finding 99 to the power of 86

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:

998699^{86}

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

99 x 99 x 99 x 99 x ... (for a total of 86 times) = 4213342221547683589715320328404409546857704031154349329931385998059963276851850573663720311246887790919404881692290237811708041831502416703427631350589356619026233196541401

Therefore, 99 to the power of 86 is 4213342221547683589715320328404409546857704031154349329931385998059963276851850573663720311246887790919404881692290237811708041831502416703427631350589356619026233196541401.
