Let's complete the tables by following the examples given.

TABLE 1A

1. $\sqrt{4 \cdot 25}$ simplifies to $\sqrt{100}$ which is equal to $10$.
2. $\sqrt{9 \cdot 36}$ simplifies to $\sqrt{324}$ which is equal to $18$.
3. $\sqrt{16 \cdot 4}$ simplifies to $\sqrt{64}$ which is equal to $8$.
4. $\sqrt{36 + 100}$ simplifies to $\sqrt{136}$ which is approximately $11.66$ (since 136 is not a perfect square).

TABLE 1B

1. $\sqrt{4} \cdot \sqrt{25}$ simplifies to $2 \cdot 5$ which is equal to $10$.
2. $\sqrt{9} \cdot \sqrt{36}$ simplifies to $3 \cdot 6$ which is equal to $18$.
3. $\sqrt{16} \cdot \sqrt{4}$ simplifies to $4 \cdot 2$ which is equal to $8$.
4. $\sqrt{36} \cdot \sqrt{100}$ simplifies to $6 \cdot 10$ which is equal to $60$.

Do you want further details on any of these calculations or have any questions?

Here are 5 questions you might want to ask:
