Math Tutor Explains: What is 77 to the Power of 42?

A math tutor would explain that to solve for 77 to the power of 42, we must first understand the structure. The number 77 is called the base, and the number 42 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: 77 to the Power of 42 is equal to 17084821953903998331261548972374174279411114015538617639889642846085207685155529

Methods

Step-by-step from math tutor: finding 77 to the power of 42

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:

774277^{42}

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

77 x 77 x 77 x 77 x ... (for a total of 42 times) = 17084821953903998331261548972374174279411114015538617639889642846085207685155529

Therefore, 77 to the power of 42 is 17084821953903998331261548972374174279411114015538617639889642846085207685155529.
