Question

Write expression in radical form!?

1.(3n)^3/4
2.(5x)^7/4
3.(4b)2/3
4.x^7/4

Answer 1

I'll do the first one to get you started

Answer 2

Use the idea that

\[\large x^{m/n} = \sqrt[n]{x^m}\]

to get

\[\large (3n)^{3/4} = \sqrt[4]{(3n)^3}\]

\[\large (3n)^{3/4} = \sqrt[4]{3^3*n^3}\]

\[\large (3n)^{3/4} = \sqrt[4]{27n^3}\]

Answer 3

Alright, for the next one, (5x)^7/4, i got \[\sqrt[4]{78125x^7}\]

Answer 4

That doesnt seem right..... @jim_thompson5910
