Here are the calculations for the square root problems.
a) $\sqrt{1} + \sqrt{9}$
Step 1: Calculate $\sqrt{1}$.
$$\sqrt{1} = 1$$
Step 2: Calculate $\sqrt{9}$.
$$\sqrt{9} = 3$$
Step 3: Add the results.
$$1 + 3 = 4$$
So, $\sqrt{1} + \sqrt{9} = \boxed{4}$.
b) $\sqrt{16} + \sqrt{144}$
Step 1: Calculate $\sqrt{16}$.
$$\sqrt{16} = 4$$
Step 2: Calculate $\sqrt{144}$.
$$\sqrt{144} = 12$$
Step 3: Add the results.
$$4 + 12 = 16$$
So, $\sqrt{16} + \sqrt{144} = \boxed{16}$.
