how to solve this >> http://puu.sh/cOIim.png
sorry cant type here lol :<
$$\\ \left(7\;\sqrt[4]{3^3}\right)^2\\\\ =\left(7\;(3^3)^{1/4}\right)^2\\\\ =7^2\;(3^3)^{1/4*2}\\\\ =49\;(3^3)^{1/2}\\\\ =49\;(27)^{1/2}\\\\ =49\;\sqrt{27}\\\\ =49\;\sqrt{9*3}\\\\ =49\times3 \;\sqrt{3}\\\\ =147\;\sqrt{3}\\\\$$
ty bro :^) sorry for being anonymous :<
