Question

Need help with 4-6 I don't understand

Answer 1

In first example it says 10^4 = --- * --- * --- * ---- 
 there are 4 solutions so we take 4th root to 10^4 which = 10 
so 10^4 = 10 * 10 *10 *10 
in second example it says 8/27 = ---- * ----- * ----- 
there are 3 solutions so we take 3th root to 8/27 which = 2/3 
 so 8/27 = 2*3 * 2/3 * 2/3 
the third example it says 64 = --- *---- *------ 
3 solutions so we take 3th root to 64 which is = 4 
so 64 = 4 * 4 * 4

Answer 2

$\frac{2}{3}* \frac{2}{3}* \frac{2}{3}= \frac{8}{27}$
