Math Tutor Explains: What is 28 to the Power of 78?

A math tutor would explain that to solve for 28 to the power of 78, we must first understand the structure. The number 28 is called the base, and the number 78 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: 28 to the Power of 78 is equal to 75566001870440058564354986955430608812402950425434437230800154595256703924897732178068663940319933671682829451264

Methods

Step-by-step from math tutor: finding 28 to the power of 78

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:

287828^{78}

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

28 x 28 x 28 x 28 x ... (for a total of 78 times) = 75566001870440058564354986955430608812402950425434437230800154595256703924897732178068663940319933671682829451264

Therefore, 28 to the power of 78 is 75566001870440058564354986955430608812402950425434437230800154595256703924897732178068663940319933671682829451264.
