x(t) * d(t-t0) = x(t0)
as per this rule

  1. at t = 3; exp(-t*t) = e^(-9) which is a constant! so pull it out of integral. integral of delta over -inf to +inf = 1;so ans = e^(-9).

  2. at t =1; 0 so ans = 0

  3. at n = 2; ans = e^(4);

Hope this helps

1)t=3, Ans=e^(-9)
2)t=1 Ans=0
3)t=2 Ans=e^4
