Math Tutor Explains: What is 28 to the Power of 89?

A math tutor would explain that to solve for 28 to the power of 89, we must first understand the structure. The number 28 is called the base, and the number 89 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: 28 to the Power of 89 is equal to 626707351931491813594120804378404577651870448613598387784608944885797157845528370220092336843414509505760263616928719215114846208

Methods

Step-by-step from math tutor: finding 28 to the power of 89

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:

288928^{89}

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

28 x 28 x 28 x 28 x ... (for a total of 89 times) = 626707351931491813594120804378404577651870448613598387784608944885797157845528370220092336843414509505760263616928719215114846208

Therefore, 28 to the power of 89 is 626707351931491813594120804378404577651870448613598387784608944885797157845528370220092336843414509505760263616928719215114846208.
