Math Tutor Explains: What is 42 to the Power of 89?

A math tutor would explain that to solve for 42 to the power of 89, we must first understand the structure. The number 42 is called the base, and the number 89 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: 42 to the Power of 89 is equal to 2945688677387183659504976648693207700546390111613723609366833545425091410949945141566710833704230892897490304424732630996097768910079278314422272

Methods

Step-by-step from math tutor: finding 42 to the power of 89

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:

428942^{89}

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

42 x 42 x 42 x 42 x ... (for a total of 89 times) = 2945688677387183659504976648693207700546390111613723609366833545425091410949945141566710833704230892897490304424732630996097768910079278314422272

Therefore, 42 to the power of 89 is 2945688677387183659504976648693207700546390111613723609366833545425091410949945141566710833704230892897490304424732630996097768910079278314422272.
