## anonymous 4 years ago Cube root p^7*r5

1. anonymous

$\sqrt[3]{p^7r^5}$ correct?

2. anonymous

Si senor!

3. anonymous

so if you just pull out the variables in 3s and leave whats left behind you would end up with...

4. anonymous

P4 R2 in the root

5. anonymous

you call pull out one more P

6. anonymous

how?

7. anonymous

At this point we have P3 R3 and inside the root p4 r 2

8. anonymous

ya but if were pulling out the variables in 3's then we can take out 2P's from that P^7

9. anonymous

well be left with P in the cube root from that variable

10. anonymous

So it would be P^2 and R1 on the outside of the cube root?

11. anonymous

correct

12. anonymous

with PR^2 on the inside

13. anonymous

and on the inside P and r2 and it would be simplified

14. anonymous

yup

Perfect! Thank you
