हल करो (i) 3sqrt(5)+2sqrt(5) (ii) 7sqrt(3)-4sqrt(3) (iii) (sqrt(2))2+(3sqrt(3))2 (iv) 23 imes 24 (v) (5)/(7) (vii) (32)4

$$(3+2)\sqrt{5} = 5\sqrt{5}$$

The answer is $\boxed{5\sqrt{5}}$.

ii)

$$(7-4)\sqrt{3} = 3\sqrt{3}$$

The answer is $\boxed{3\sqrt{3}}$.

iii)

$$(\sqrt{2})^2 = 2$$ $$(3\sqrt{3})^2 = 3^2 \times (\sqrt{3})^2 = 9 \times 3 = 27$$

$$2 + 27 = 29$$

The answer is $\boxed{29}$.

iv)

$$2^{3+4} = 2^7 = 128$$

The answer is $\boxed{128}$.

v)

$$5^{7-2} = 5^5 = 3125$$

The answer is $\boxed{3125}$.

vi)

$$3^{2 \times 4} = 3^8 = 6561$$

The answer is $\boxed{6561}$.

Q2: जोड़िए (Add)

i)

$$\frac{2}{3} = \frac{2 \times 10}{3 \times 10} = \frac{20}{30}$$ $$\frac{3}{10} = \frac{3 \times 3}{10 \times 3} = \frac{9}{30}$$

$$\frac{20}{30} + \frac{9}{30} = \frac{20+9}{30} = \frac{29}{30}$$

The answer is $\boxed{\frac{29}{30}}$.

iii)

$$\frac{28}{8} + \frac{5}{8} = \frac{28+5}{8} = \frac{33}{8}$$

The answer is $\boxed{\frac{33}{8}}$.
