\sqrt[5]{(x^7)^3}\implies \sqrt[5]{x^{7\cdot 3}}\implies \sqrt[5]{x^{21}}\implies x^{\cfrac{}{}\frac{21}{5}}$

The function f(x) varies directly with x, and f(x)=12 when x=8

lozanna [386]

The answer would be d.

You can solve this by changing it up a little, such as changing it to f • x = 12
you can then divide by 8, because x = 8.
You're then left with f = 12/8 or 3/2
multiply by x again on both sides, and voila, f(x)=3/2x
