cls wrote: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
cls wrote: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.
(answer R=3, K=2/3)
