Math Tutor Explains: What is 69 to the Power of 99?

A math tutor would explain that to solve for 69 to the power of 99, we must first understand the structure. The number 69 is called the base, and the number 99 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: 69 to the Power of 99 is equal to 111188528575236352479290820675434984468674462236930790340890942438613471750967924767808120428770821795644189335110194745773802955914255623960532105077288980562793213740472496404484029

Step-by-step from math tutor: finding 69 to the power of 99

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:

699969^{99}

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

69 x 69 x 69 x 69 x ... (for a total of 99 times) = 111188528575236352479290820675434984468674462236930790340890942438613471750967924767808120428770821795644189335110194745773802955914255623960532105077288980562793213740472496404484029

Therefore, 69 to the power of 99 is 111188528575236352479290820675434984468674462236930790340890942438613471750967924767808120428770821795644189335110194745773802955914255623960532105077288980562793213740472496404484029.
