Question

Find the values of constants r and k

Answer 1

\[\frac{r^2}{4}(3x)^r(\frac{2}{9x^2})^{6-r}\]

Answer 2

We will need more information. Is there some other given you can let us see?

Answer 3

Regarding k at least.

Answer 4

this is just an expression

Answer 5

Sorry, forgot the 2nd part of the question:
The above equation can be simplified to \[\frac{k}{x^3}\]

Answer 6

This still doesn't really help us "find a value". With two variables, there needs to be two equations. You've given us 3 variables... x, r, and k.

Answer 7

hmmm... this is all the info I am given

Answer 8

Are they looking for a value with a variable?

Answer 9

No. But the answers are r = 3, k = 2/3
