Answer 1

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

Answer 2

Si senor!

Answer 3

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

Answer 4

P4 R2
in the root

Answer 5

you call pull out one more P

Answer 6

how?

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

correct

Answer 12

with PR^2 on the inside

Answer 13

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

Answer 14

yup

Answer 15

Perfect! Thank you
