Math Tutor Explains: What is 28 to the Power of 82?

A math tutor would explain that to solve for 28 to the power of 82, we must first understand the structure. The number 28 is called the base, and the number 82 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 82 is equal to 46447096445677204636932178862077156290196347896695829450534699822902104607661940469642972702901289150901881219196125184

Methods

Step-by-step from math tutor: finding 28 to the power of 82

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:

288228^{82}

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

28 x 28 x 28 x 28 x ... (for a total of 82 times) = 46447096445677204636932178862077156290196347896695829450534699822902104607661940469642972702901289150901881219196125184

Therefore, 28 to the power of 82 is 46447096445677204636932178862077156290196347896695829450534699822902104607661940469642972702901289150901881219196125184.
