The Power of a Power Rule
Simplify. All variables represent nonzero real numbers.
5y^4(y^5)^2 / 15y^7(y^2)^3
I got:
5y^40 / 15y^42
Is this correct?

Math 
bobpursley,
no. In the numberator, y^5 squared is y^10. That times y^4 is y^14
In the denominator, y^2 cubed is y^6, and that times y^7 is y^13
then y^14/y^13 is y

Help!,
Thanks. See my other post for a comment.

Cuddle Bunny,
Wow... this is all the way from 2009 and I'm commenting on this in 2016. Really scary...
