Question

(solving equations using square and cube roots lc) determine the value of b in the equation b3 = −216. b = −72 b = −6 b = 6 b = 72

Answer 1

To solve for b in the equation b^3 = -216, one needs to calculate the cube root of -216, which is -6.

Step-by-step explanation:

The student is asked to determine the value of b in the equation b3 = -216.

To solve for b, we need to find the cube root of -216.

Since the cube root of a negative number is negative and the cube root of 216 is 6 (as 6 x 6 x 6 = 216),

the solution for b is b = -6.
