Math Tutor Explains: What is 74 to the Power of 90?

A math tutor would explain that to solve for 74 to the power of 90, we must first understand the structure. The number 74 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: 74 to the Power of 90 is equal to 1701589416883577093123171337392010565643112981427374828771639522068697348577696960508162328768964210428244817355101150510575793739189996455462382009371037735921570021376

Methods

Step-by-step from math tutor: finding 74 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:

749074^{90}

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

74 x 74 x 74 x 74 x ... (for a total of 90 times) = 1701589416883577093123171337392010565643112981427374828771639522068697348577696960508162328768964210428244817355101150510575793739189996455462382009371037735921570021376

Therefore, 74 to the power of 90 is 1701589416883577093123171337392010565643112981427374828771639522068697348577696960508162328768964210428244817355101150510575793739189996455462382009371037735921570021376.
