So I came upon the expression -x-1/3 (1-x2/3)1/2, that when simplified is -(x-2/3-1)1/2
I have tried many times but I din't know how to simplify it. ¿How can I do it?
Since \(\displaystyle (x^2)^{1/2}= x\) (I'm assuming x is positive), going the other way, \(\displaystyle x(anything)^{1/2}= (x^2(anything))^{1/2}\). In particular \(\displaystyle -x^{-1/3}(1- x^{2/3})^{1/2}= -(x^{-2/3}(1-x^{2/3}))^{1/2}= -(x^{-2/3}- x^{-2/3+ 2/3})^{1/2}= -(x^{-2/3}- x^0)^{1/2}= -(x^{-2/3}- 1)^{1/2}\).
