8 ln x -(1/3) ln y

Choose one answer.

a. ln x^8 y^3

b. ln x^8 /3"sqrt"y

c. ln x^8 3"sqrt"y

d. ln x^8/y^3

The answer I originally came up with, was ln(x^8y^3), but this is not an option, since answer a does not have parenthesis.

= ln(x^8) - ln(y^(1/3))

= ln (x^8/(y^(1/3))

if in b)

you mean ln(x^8/cuberoot(y))

that would be it, and the same as mine
