I'll start by solving the first few problems from the image for you. These are square root simplifications involving variables and exponents.

### 1. \(\sqrt{40a^4b^3c^2}\)
We simplify this square root as follows:
- \(\sqrt{40}\) simplifies to \(2\sqrt{10}\) because \(40 = 4 \times 10\) and \(\sqrt{4} = 2\).
- For \(a^4\), \(\sqrt{a^4} = a^2\).
- For \(b^3\), \(\sqrt{b^3} = b\sqrt{b}\).
- For \(c^2\), \(\sqrt{c^2} = c\).

Thus, \(\sqrt{40a^4b^3c^2} = 2a^2bc\sqrt{10b}\).

### 2. \(\sqrt{49a^2b^5}\)
- \(\sqrt{49} = 7\).
- \(\sqrt{a^2} = a\).
- \(\sqrt{b^5} = b^2\sqrt{b}\).

So, \(\sqrt{49a^2b^5} = 7ab^2\sqrt{b}\).

---

### 3. \(\sqrt{121p^4q^9r^2}\)
- \(\sqrt{121} = 11\).
- \(\sqrt{p^4} = p^2\).
- \(\sqrt{q^9} = q^4\sqrt{q}\).
- \(\sqrt{r^2} = r\).

Thus, \(\sqrt{121p^4q^9r^2} = 11p^2q^4r\sqrt{q}\).

---

### 4. \(\sqrt{36a^2b^5c^2}\)
- \(\sqrt{36} = 6\).
- \(\sqrt{a^2} = a\).
- \(\sqrt{b^5} = b^2\sqrt{b}\).
- \(\sqrt{c^2} = c\).

So, \(\sqrt{36a^2b^5c^2} = 6ab^2c\sqrt{b}\).

---

### 5. \(\sqrt{144a^6b^2c^2}\)
- \(\sqrt{144} = 12\).
- \(\sqrt{a^6} = a^3\).
- \(\sqrt{b^2} = b\).
- \(\sqrt{c^2} = c\).

Thus, \(\sqrt{144a^6b^2c^2} = 12a^3bc\).
