СРОЧНО (a++2)·[tex\frac{1}{a+1} [/tex]=

Answer 1

$(a+ \frac{1}{2} + 2) * \frac{1}{a+1} = (a + \frac{5}{2}) * \frac{1}{a+1} = \frac{a}{a+1} + \frac{5a}{2a+2} = \frac{2a+5a}{2a+2} = \frac{7a}{2a+2}$

Answer 2

I'm sorry, but your expression is incomplete. It appears to be missing the dividend of the division operation. Please provide the full expression, including the dividend, so I can help you evaluate it.
