If Q= L(to the power of 3/5) x K(to the power of 3/5), why is Q(to the
power of 5/3) = L x K??  And if Q = L(power 1/2) x K(power1/2) what is
L x K equal to??

Because I am a new user I don't have a right to provide answer yet, so
I provide the answer here.

Have fun



If Q= L(to the power of 3/5) x K(to the power of 3/5)

Q= L x K (to the power of 3/5)

We can take power of 5/3 of each side. If we do that,

 Q (to the power of 5/3) = L x K (No power because 3/5 x 5/3 = 1)



if Q = L(power 1/2) x K(power1/2) 

Q = L x K (power of 1/2)

We can take power of 2 (square) of each side. If we do that,

Q² [or Q (power 2)]= Lx K (No power because 1/2 x 2 = 1)

So, L x K =Q²

Thanks very much - Seems simple now it's done.
