Posted by ameme on Sunday, June 23, 2013 at 10:07pm.

I need help with a few problems.

1.) (x^3/4 times y^1/3)^2/3

How is the answer x^1/2y^2/9

2.)(x^-1/3 times y) (x^1/2 times y^-4/3)
How is the answer x^1/6 over y^1/3

3.)(4a^2b^-7/2)^1/2
How is the answer 2a over b^3/4

4.) (x^2/3y^-1/3 over 8x^1/2y)^1/3
How is the answer x^1/18 over 2y^4/9

5.)(50x^3/4y/2x^1/2)+(x^1/2y^1/2/9x^3/4y^3/2)^-1/2

How is the answer 8x^1/8y^1/2

Please help explain so I can understand. Thank you!
