Math Tutor Explains: What is 45 to the Power of 87?

A math tutor would explain that to solve for 45 to the power of 87, we must first understand the structure. The number 45 is called the base, and the number 87 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: 45 to the Power of 87 is equal to 675287480916119557539451818816740997089009559913482951650119698139327568517835934843681926586314928574912574976707446694490499794483184814453125

Methods

Step-by-step from math tutor: finding 45 to the power of 87

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:

458745^{87}

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

45 x 45 x 45 x 45 x ... (for a total of 87 times) = 675287480916119557539451818816740997089009559913482951650119698139327568517835934843681926586314928574912574976707446694490499794483184814453125

Therefore, 45 to the power of 87 is 675287480916119557539451818816740997089009559913482951650119698139327568517835934843681926586314928574912574976707446694490499794483184814453125.
