Math Tutor Explains: What is 75 to the Power of 90?

A math tutor would explain that to solve for 75 to the power of 90, we must first understand the structure. The number 75 is called the base, and the number 90 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: 75 to the Power of 90 is equal to 5695261966737109423145001531440800778122406247162532711247345408519926182418819770852358625146574698466916179116671432623039369493034289604338482604362070560455322265625

Methods

Step-by-step from math tutor: finding 75 to the power of 90

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:

759075^{90}

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

75 x 75 x 75 x 75 x ... (for a total of 90 times) = 5695261966737109423145001531440800778122406247162532711247345408519926182418819770852358625146574698466916179116671432623039369493034289604338482604362070560455322265625

Therefore, 75 to the power of 90 is 5695261966737109423145001531440800778122406247162532711247345408519926182418819770852358625146574698466916179116671432623039369493034289604338482604362070560455322265625.
