Question

What is the value of b in the equation (y^b)^4=1/y^24?
A.) -20
B.)-6
C)6
D.)20

Answer 1

Answer:

b  = 6

Step-by-step explanation:

In (y^b)^4=1/y^24 we can re-write (y^b)^4 as y^(4b) and then equate this result to y^24.  Setting the exponents equal to one another, we get 4b = 24, or b = 6.
