Answer 1

Answer:

1)100000

2)64/65

3)6

4)256

Answer 2

(i) 2⁵ × 5⁵

{ Use aᵐ × bᵐ = (a×b)ᵐ }

➝ (2×5)⁵

➝ 10⁵

➝ 100000

_______________________________________________

$\sf \bold{(ii)} \: \: \dfrac{5}{13} + \dfrac{3}{5} \\ \\ \sf \: take \: lcm\\ \sf \implies \: \dfrac{(5 \times 5) + (3 \times 13)}{5 \times 13} \\ \\ \sf \implies \: \dfrac{25 + 39}{65} \\ \\ \sf \implies \: \: \bold{\dfrac{64}{65} }$

_______________________________________________

$\sf \bold{(iii)} \: \: \dfrac{3}{16} \times \dfrac{2}{15} \\ \\ \sf \implies \: \: \: \dfrac{2}{16} \times \dfrac{3}{15} \\ \\ \sf \implies \: \: \dfrac{1}{8} \times \dfrac{1}{5} \\ \\ \sf \implies \: \: \bold{\frac{1}{40} }$

(iv) (2³×2)²

➝ (2×2×2×2)²

➝ (16)²

➝ 256

ANSWER :

$\sf \: \bold{(i) \: \: 100000} \\ \\ \sf \: \bold{(ii) \: \: \dfrac{64}{65} } \\ \\ \sf \bold{(iii) \: \dfrac{1}{40} \: } \\ \\\sf\bold{(iv)256}$
