Homework Help: maths

Posted by needhelpplease on Saturday, June 2, 2007 at 9:44pm.

Can someone please help me with solving this equation (I dont know how to do it with the fractions)

1/3 x1^-2/3 . x2^2/3
--------------------
2/3 x1^1/3 . x2^-1/3

how do I cancel out some of the terms and reduce it down so that Im left with x2 on top and x1 on bottom??

And please explain it because I dont know how to cancel out with fractions.

Thanks xx

Add the fractions

a^b * a^c= a^b+c

it probably doesnt show that well but one is x1 and the other x2 so you can add their fractions
