anonymous · Answer

how did you do it

anonymous · Answer

becuase i tried and i couldnt get anything right

anonymous · Answer

can you explain what you did but i dont know what you did

hero · Answer

Yeah, in vyew

anonymous · Answer

Hero i understand it now

anonymous · Answer

even though you didnt finish explaining it

anonymous · Answer

I THINK hes working on it so just relax..

anonymous · Answer

@Hero i think u r wrong....
2X =X+X NOT X*X......

hero · Answer

s = p^9
s + s/r = p^9 + p^9/p^6
           = p^9 + p^3
           = p^3^3 + p^3^1
           = p^3(3+1)
           = p^3^4
           = p^12

Therefore, C

anonymous · Answer

$$a^{n}a^{m}= a^{n+m}$$

$$\frac{a^{m}}{a^{n}}=a^{m-n}$$
use these properties to solve this question!!

hero · Answer

If you have the solution, post it

anonymous · Answer

$$p^{9} p^{9}=p^{9+9}=p^{18}=s^{2}$$


$$\frac{s^{2}}{r}=\frac{p^{18}}{p^{6}}$$

$$\frac{s^{2}}{r}=p^{12}$$
