Answer:
c. Mutation
Step-by-step explanation:
should be right I hope lol. good luck :)
I think what you need to do is make B = -5
3a = -2(-5) - 7

This is a lowest common multiple question.
to find the lowest common multiple, you need to find the prime factors of the two numbers:


Take out duplicates:

and multiply them together:

and that is your answer.
Easy peasy.
Fourth root (3/2x)
= [fourth root {3*(2x)^3} / {2x * (2x)^3}]
= [fourth root (3*8x^3}) /(2x)^4]
= [fourth root (24x^3)] / 2x
answer is B. second one
