1) When Sam and Wendy work together it takes 6 days to wash the windows in a building. If it takes Sam 9 days longer than Wendy to wash them by himself, how long would it take each to complete the job working alone.

2) x=\frac{2ab}{a-b} : solve for b :solve for b

3) -27^{\frac{-2}{3}}+\frac{1}{256^{\frac{-3}{8}}}

4) (\frac{81m^{\frac{1}{4}}n}{m^{-4}n^{\frac{2}{3}}})^{\frac{1}{2}} * the prantheses over the expression

5) (2?3-3?x) (5?2-?x)

6) f(-6)= \frac{x+5}{x^{3}-3x^{2}-10x}

7) \frac{2x}{x^{2}+5x+6}-\frac{x+1}{x^{2}+2x-3}

8) solve for x: \frac{2}{x+2}-\frac{5x+6}{x^{2}-x-6}=\frac{-x}{x-3}
