Question

What is the solution to the equation? ^5√x+7 = -2 (Please help!)

A. -39

B. -17

C. 25

D. no solution

Answer 1

Step-by-step explanation:

Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S

so we get as,

==> x+7 = (-2)^5

==> x+7 = -32

==> x = -32-7

==> x = -39

hence, x = -39

Option A.) is correct.
