Question

como resolver 8^1/3+(1/9)^1/2+16^1/4

Answer 1

Utilize as regras de potenciação. :)

$8^{ \frac{1}{3} }+ \frac{1}{9}^{ \frac{1}{2} } +16^{ \frac{1}{4} } \\ \\ (2^3)^{ \frac{1}{3} }+ (3^{-2})^{ \frac{1}{2} } +(2^4)^{ \frac{1}{4} } \\ \\ (2)^{ \frac{3}{3} }+ (3)^{ -\frac{2}{2} } +(2)^{ \frac{4}{4} } \\ \\ 2+3^{-1}+2 \\ \\ 4+ \frac{1}{3} \\ \\ \frac{13}{3}$
