not totally sure. I wouldn't trust this to be right.

First you could call this "distributing" the exponent, not sure what the real name is for this step.



Now all terms with negative exponents in the numerator go to the denominator and lose the negative sign and vice versa.



Now multiply the things in the numerator and the things in the denominator together.



Now reduce the fraction by 18x5



Same as guest. smiley
