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

A math tutor would explain that to solve for 87 to the power of 45, we must first understand the structure. The number 87 is called the base, and the number 45 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: 87 to the Power of 45 is equal to 1898306644365230277162087489060194804678355249134085844533526530426857230579651774396407

Methods

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

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:

874587^{45}

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

87 x 87 x 87 x 87 x ... (for a total of 45 times) = 1898306644365230277162087489060194804678355249134085844533526530426857230579651774396407

Therefore, 87 to the power of 45 is 1898306644365230277162087489060194804678355249134085844533526530426857230579651774396407.
