Answer 1

a) (2/3)⁵ × (2/3)⁴ = (2/3)⁵+⁴ = (2/3)⁹

b) (5/7)⁸ : (5/7)⁶ = (5/7)⁸-⁶ = (5/7)²

c) [(5/7)²]³ = (5/7)²×³ = (5/7)⁶

d) (4/5)⁶ × (7/8)⁶ = (4/5 × 7/8)⁶ = (1/5 × 7/2)⁶ = (7/10)⁶

$e)(( \frac{ {2}^{2} \times 3}{3 \times 5} ) {}^{3} ) {}^{20} = ( \frac{2 {}^{2} \times 3 }{3 \times 5} ) {}^{60} = ( \frac{4}{5} ) {}^{60}$
