What radicals? Need to repost in clearer terms.
I tried using the symbol but it will does not recognize it here. It's the check mark with a horizontal line.

3^symbol over y^4 3^symbol over 81y^3
still not totally clear.

is it 3√(y^4)*(3√ 81)y^3 or
is it 3√(y^4)*3√(81y^3) ?

(on a PC, I get the √ sign by holding down the Alt key then typing 251 on the number pad, then releasing the Alt key)
3�ã(y^4)*3�ã(81y^3)

This one.

Thanks!
