root(3)(4^4)

Explanation:

a^(color(red)n/color(green)m)=root(color(green)m)(a^color(red)n)

So 4^(color(red)4/color(green)3)=root(color(green)3)(4^color(red)4)

See the entire solution process below:

Explanation:

First, we can use this rule of exponents to rewrite the expression:

x^(color(red)(a) xx color(blue)(b)) = (x^color(red)(a))^color(blue)(b)

4^(4/3) = 4^(color(red)(4) xx color(blue)(1/3)) = (4^color(red)(4))^color(blue)(1/3) = 256^(1/3)

We can now use this rule of exponents to write this expression in radical form:

x^(1/color(red)(n)) = root(color(red)(n))(x)

256^(1/color(red)(3)) = root(color(red)(3))(256)
