The question I had was

Would it be correct to take out the $10$ because it is a constant, find the Laplace transform of $e^{-200t}$ and then multiply it by the Laplace transform of $u(t)$ to obtain a final answer of $$10\left(\frac{1}{s+200}\right)\left(\frac1s\right).$$ The $u(t)$ is what is really confusing me in this problem.
