Math Tutor Explains: What is 81 to the Power of 58?

A math tutor would explain that to solve for 81 to the power of 58, we must first understand the structure. The number 81 is called the base, and the number 58 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: 81 to the Power of 58 is equal to 492188083828464259642619240437945726977956569429523221310692359667343884422109547118921290830957809710528855841

Methods

Step-by-step from math tutor: finding 81 to the power of 58

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:

815881^{58}

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

81 x 81 x 81 x 81 x ... (for a total of 58 times) = 492188083828464259642619240437945726977956569429523221310692359667343884422109547118921290830957809710528855841

Therefore, 81 to the power of 58 is 492188083828464259642619240437945726977956569429523221310692359667343884422109547118921290830957809710528855841.
