Math Tutor Explains: What is 22 to the Power of 87?

A math tutor would explain that to solve for 22 to the power of 87, we must first understand the structure. The number 22 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: 22 to the Power of 87 is equal to 617693784826781208103305209674415984584107612553028219909543618275545250274852308867934100593113681065193069701234688

Methods

Step-by-step from math tutor: finding 22 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:

228722^{87}

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

22 x 22 x 22 x 22 x ... (for a total of 87 times) = 617693784826781208103305209674415984584107612553028219909543618275545250274852308867934100593113681065193069701234688

Therefore, 22 to the power of 87 is 617693784826781208103305209674415984584107612553028219909543618275545250274852308867934100593113681065193069701234688.
