Math Tutor Explains: What is 91 to the Power of 50?

A math tutor would explain that to solve for 91 to the power of 50, we must first understand the structure. The number 91 is called the base, and the number 50 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: 91 to the Power of 50 is equal to 89550830124054857260332111446785195574263739255179823926331144600841049517412867188485189905327001

Methods

Step-by-step from math tutor: finding 91 to the power of 50

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:

915091^{50}

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

91 x 91 x 91 x 91 x ... (for a total of 50 times) = 89550830124054857260332111446785195574263739255179823926331144600841049517412867188485189905327001

Therefore, 91 to the power of 50 is 89550830124054857260332111446785195574263739255179823926331144600841049517412867188485189905327001.
