Evaluate the expression (9x)^2/3 + (2y)^2/3 + z^2/3 using x = 3, y = 4, z = -1​.

Show us what you have tried GM.

 

 

some hints:    (not necessarily a part of this particular question, just a few of the 'rules'.)

 

\((9x)^5  =  9^5  *  x^5\\ 16^{2/3}=16^{1/3}*16^2\\ 16^{2/3}=16^{2}*16^{1/3}\\ (-1)^2=1\)
