Simplify:
[(x^3)x]/[(x^2)1]

x^3x = x(x^21)

I don't get it...

AP Calc.  Steve, Friday, July 12, 2013 at 12:53pm
sure you do. factor out x^21 top and bottom

AP Calc.  Anon, Friday, July 12, 2013 at 12:54pm
but don't you have to get rid of the negative exponents somehow..?

AP Calc.  Steve, Friday, July 12, 2013 at 12:56pm
sorry. I missed the negative exponents.
(x^3  x)/(x^(2)1)
(1  x^4)/x^3 / (1x^2)/x^2
(1x^4)/x^3 * x^2/(1x^2)
(1x^2)(1+x^2) / x(1x^2)
(1+x^2)/x

How did you go from the original question to the 1st step?

AP Calc.  Steve, Friday, July 12, 2013 at 12:59pm
1/x^3  x
over a common denominator of x^3, x = x^4/x^3
