Question

Determine the value of b.

b3 = -125







Notes

b3 is read as "b cubed"

Equations are solved with inverse operations.

What is the inverse of cubing a value or using an exponent of 3?

Group of answer choices

b = -41.7

b = ±5

b = -5

Answer 1

b = -5

Reason: take the cube root (inverse of cubing): b = ∛(−125) = −5 because (−5)^3 = −125.
