Question

What is the approximate solution to this equation?

x³ = 124.75

A.X=4
B.X=5
C.X=8
D.X=10

Answer 1

So you could take and do each number to the third power until you get approximately 124.75.

Starting with A. it would be 4x4x4 = 64 - So it can't be A.

Now, B. it would be 5x5x5 = 125 - This would be your answer since the other numbers just get bigger and stray farther and farther away from 124. Hope this helps :)

Answer 2

the answer is B because 5^3 is 125 so the approximate answer is 124.75
