Math Tutor Explains: What is 84 to the Power of 68?

A math tutor would explain that to solve for 84 to the power of 68, we must first understand the structure. The number 84 is called the base, and the number 68 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: 84 to the Power of 68 is equal to 70956380217803779648809210276683410797791546657546825695575820281309763882038038174497471377988158609059217703481922032785629904896

Methods

Step-by-step from math tutor: finding 84 to the power of 68

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:

846884^{68}

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

84 x 84 x 84 x 84 x ... (for a total of 68 times) = 70956380217803779648809210276683410797791546657546825695575820281309763882038038174497471377988158609059217703481922032785629904896

Therefore, 84 to the power of 68 is 70956380217803779648809210276683410797791546657546825695575820281309763882038038174497471377988158609059217703481922032785629904896.
