### Re: Need help on this Simplification of ALgebra

Thank you for the great help !!
so i work out as -
X^(R-2(6-R)) = X^-3
R-12+2R=-3
3R=9
R=3

and K can then be solved !!!

### Re: Need help on this Simplification of ALgebra

x=X, sorry for the typo.

The recent topic learnt is Exponential Equation.
the complete question is as follow -

If (R^2)/4 * (3X)^R * (2/9X^2)^(6-R) can be simplified to K/X^3 , find the values of the constants R and K.

### Need help on this Simplification of ALgebra

the below is to be simplify to 2/3X^2 but i just can't get it -:(
(R^2)/4 * (3x)^R * (2/9x^2)^(6-R) = 2/3X^2 -- proof it (R is eventually eliminated- how ??)

main obstacles is i can't get rid of the ^R, pls help
