Math Tutor Explains: What is 84 to the Power of 56?

A math tutor would explain that to solve for 84 to the power of 56, we must first understand the structure. The number 84 is called the base, and the number 56 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 56 is equal to 574963160960863974930849547429534833696074031381500767474884369606690548344519012015038423181171376957423616

Methods

Step-by-step from math tutor: finding 84 to the power of 56

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:

845684^{56}

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

84 x 84 x 84 x 84 x ... (for a total of 56 times) = 574963160960863974930849547429534833696074031381500767474884369606690548344519012015038423181171376957423616

Therefore, 84 to the power of 56 is 574963160960863974930849547429534833696074031381500767474884369606690548344519012015038423181171376957423616.
