G(S)=2/s(e^-3s_e^-4s)

G(S)=(2S+1/S^2)*e^-2s_(3s+1/s^2)*e-3s

find g(t)????

First off, what work have you already done?
Second, what operation does '_' represent in e^-3s_e^-4s? If it's multiplication, you can write it as (e^(-3s)*e^(-4s))
Third, without parentheses, it's difficult to tell what's in the numerator of a rational expression, and what's in the denominator. E.g., does (2S + 1/S^2) in your second problem mean
$$2S + \frac{1}{S^2}$$
or
$$\frac{2S + 1}{S^2}$$?
