|dw:1359250931912:dw|

2. MariaB2014

thats to the 1/3 power.

3. MariaB2014

all the numbers are to the power.

4. MariaB2014

$(27p ^{3}q ^{6}r ^{-1})\frac{ ^{1} }{ 3 }$

5. Mertsj

What is the third root of 27?

6. MariaB2014

sorry about the delay , 3

7. Mertsj

And what is the third root of p^3?

8. MariaB2014

p cubed ?

9. Mertsj

Yes. What is the third root of p cubed?

10. MariaB2014

p ?

11. Mertsj

$\sqrt[3]{p^{3}}=$

12. Mertsj

Yes p.

13. Mertsj

What is the third root of p to the sixth?

14. MariaB2014

p?

15. Mertsj

no.

16. Mertsj

$\sqrt[3]{p^6} =$

17. MariaB2014

a little help ?

18. Mertsj

$p ^{\frac{6}{3}}$

19. MariaB2014

p squared .

20. Mertsj

yes.

21. MariaB2014

okay.

22. Mertsj

When you raise to a power, you multiply the exponents.

23. MariaB2014

okay.

24. Mertsj

$(27p^3q^6r ^{-1})^{\frac{1}{3}}=3pq^2r ^{-\frac{1}{3}}$

25. MariaB2014

THANK YOU ! i understood it perfectly. these problems are made seem so hard but you made it so easy !

26. Mertsj

Good for you!!
