Question #cb023

Answer 1

`(16a)^(3/4)=color(green)(8root(4)(a^3))`

Explanation:

`(16a)^(3/4)`
`color(white)("XXX")=16^(3/4) * a^(3/4)`

`color(white)("XXX")=(16^(1/4))^3 * (a^3)^(1/4)`

`color(white)("XXX")=(root(4)(16))^3 * root(4)(a^3)`

`color(white)("XXX")=2^ 3 * root(4)(a^3)`

`color(white)("XXX")=8root(4)(a^3)`
