выполните умножение (a3+ba2)/(a-b)*(a2-b2)/(a2+2ab+b2)*(1/a+1/b)    

[latex]\frac{a^3+ba^2}{a-b}*\frac{a^2-b^2}{a^2+2ab+b^2}*(\frac{1}{a}+\frac{1}{b})=\frac{ab+a^2}{b}\\ 1)\frac{a^3+ba^2}{a-b}*\frac{a^2-b^2}{a^2+2ab+b^2}=\frac{a^2(a+b)}{a-b}*\frac{(a-b)(a+b)}{(a+b)(a+b)}=a^2\\ 2) a^2*(\frac{1}{a}+\frac{1}{b})=a^2*\frac{b+a}{ab}=\frac{a(b+a)}{b}=\frac{ab+a^2}{b} [/latex]
