Math Tutor Explains: What is 72 to the Power of 98?

A math tutor would explain that to solve for 72 to the power of 98, we must first understand the structure. The number 72 is called the base, and the number 98 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 98 is equal to 104372154930143689662623670235523060734799013049885257644913580114119544295339458087510384744701252544904780174479812078495136056734464849379882407041158406545459210376166847979454464

Methods

Step-by-step from math tutor: finding 72 to the power of 98

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:

729872^{98}

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

72 x 72 x 72 x 72 x ... (for a total of 98 times) = 104372154930143689662623670235523060734799013049885257644913580114119544295339458087510384744701252544904780174479812078495136056734464849379882407041158406545459210376166847979454464

Therefore, 72 to the power of 98 is 104372154930143689662623670235523060734799013049885257644913580114119544295339458087510384744701252544904780174479812078495136056734464849379882407041158406545459210376166847979454464.
