Math Tutor Explains: What is 72 to the Power of 64?

A math tutor would explain that to solve for 72 to the power of 64, we must first understand the structure. The number 72 is called the base, and the number 64 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: 72 to the Power of 64 is equal to 74008188073452140380680373350129640905732747809179406226295452126293646901456734013952971364258988367334184692068909056

Step-by-step from math tutor: finding 72 to the power of 64

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:

726472^{64}

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

72 x 72 x 72 x 72 x ... (for a total of 64 times) = 74008188073452140380680373350129640905732747809179406226295452126293646901456734013952971364258988367334184692068909056

Therefore, 72 to the power of 64 is 74008188073452140380680373350129640905732747809179406226295452126293646901456734013952971364258988367334184692068909056.
