How do you simplify this expression, assuming all variables are positive?

(3a^1/2b^1/3)^2

The carrot symbol represents exponents.

It is a^1/2 and b^1/3, just so you know.

Square each term in the parenthesis.

3^2 = 9

(a^1/2)^2 = a

(b^1/3)^2 = b^2/3

Put it all together: 9 a b^2/3

I hope this helps.

thank you
