Answer 1

$131)\ (frac{a}{a-b}-frac{a}{a+b})*frac{a+b}{a}\ frac{a+b}{a-b}-frac{a+b}{a+b}\ frac{a+b}{a-b}-1\ frac{2b}{a-b}\ 132)\ (frac{b}{a-b}-frac{b}{a+b})*frac{a-b}{b} frac{a-b}{a-b}-frac{a-b}{a+b}\ 1-frac{a-b}{a+b}\ frac{a+b-a+b}{a+b}\ frac{2b}{a+b}$

$133)\ (frac{a}{c}+frac{c}{a}-2)*frac{1}{a-c}\ (frac{a^2+c^2-2ac}{ac}*frac{1}{a-c}\ (frac{(a-c)^2}{ac}*frac{1}{a-c}\ frac{a-c}{ac}\ 134)\ (frac{a}{b}+frac{b}{a}+2)*frac{1}{a+b}\ frac{(a+b)^2}{ab}*frac{1}{a+b}\ frac{a+b}{ab}\ 135)\ frac{(c+1)^2}{c-1}*frac{1}{c+1}\ frac{c+1}{c-1}\ 136)\ (y+frac{4y+1}{y-2})*frac{1}{y+1}\ frac{(y+1)^2}{y-2}*frac{1}{y+1}\ frac{y+1}{y-2}$
