Math Tutor Explains: What is 47 to the Power of 91?

A math tutor would explain that to solve for 47 to the power of 91, we must first understand the structure. The number 47 is called the base, and the number 91 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: 47 to the Power of 91 is equal to 144845521639389021071704401212087748776047428642231935078206137909676809751807897994352089243327500744632675706354486130610785140518879848489504921881103

Methods

Step-by-step from math tutor: finding 47 to the power of 91

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:

479147^{91}

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

47 x 47 x 47 x 47 x ... (for a total of 91 times) = 144845521639389021071704401212087748776047428642231935078206137909676809751807897994352089243327500744632675706354486130610785140518879848489504921881103

Therefore, 47 to the power of 91 is 144845521639389021071704401212087748776047428642231935078206137909676809751807897994352089243327500744632675706354486130610785140518879848489504921881103.
