Which expressions are equivalent to (k^(1/8))^(−1) ? choose all answers that apply: a. (k^(-1))^(1/8) b. (8_/`k)^(-1) c. k^(-1/8) d. none of the above * _/` is a radical with 8 as the index and k as the radicand

The first option is correct: we have

The second option is also correct, because it simply applies the definition

The third option is also correct, because it applies the rule

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
