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)
Ah. That's a different thing entirely from what I'd thought was meant. But it gives us more to work with.
When you're not sure what to do, do whatever you know, and see if that leads anywhere helpful. In this case, you have:. . . . .
We are given that this simplifies to K/x3
. Since we have a power of R on x and a power of 6 - R on x^2, and since we have x3
in the answer, then it must be that xR
divided by (x2
simplify to x3
. What can you learn about R from this?
And so forth.
