hello everyone,

I have a problem, if anyone can get me started. Thanks

I have to show this equality knowing that a and b are positive and they do not euqal 0:

$$(a^{2}+a^{\frac{4}{3}}b^{\frac{2}{3}})^{\frac{1}{2}} + (b^{2}+a^{\frac{2}{3}}b^{\frac{4}{3}})^{\frac{1}{2}} =(a^{\frac{2}{3}}+b^{\frac{2}{3}})^{\frac{3}{2}}$$

now I have no idea where to start!
