# Math Help - Simplifying a fractional base to exponent

1. ## Simplifying a fractional base to exponent

Hi is there any way I can simplify this large expression?

$\displaystyle{\frac{1}{3}\displaystyle{(}\frac{450 0-x^2}{2}\displaystyle{)}^{-\frac{2}{3}}}$

I get three fraction bars if I change the exponent so I tried to multiply the 3 inside the denominator. I'm just wondering if there's a better or any further way I can do and take this?

2. Not sure if this is any simplier but

$\frac{1}{3}\sqrt[3]{\frac{4}{(4500-x^2)^2}}$

Thanks! If I multiply the surd-fraction into the top of 1/3, is there a way I can get rid of the denominator 3?

4. I'm not understanding. The one third did not have a fractional exponent.
