Answer 1

Ответ:

1)

а) x³ × x⁵ × x = x⁹

b) x²⁰ : x : x¹⁴ = x⁵

c) (x⁸)³ : x¹⁶ = x²⁴ : x¹⁶ = x⁸

d) x⁸ : x⁵ × (x²)² = x³ × x⁴ = x⁷

e) (x⁶)³ : (x³)⁵ = x¹⁸ : x¹⁵ = x³

f) x¹² × x⁷/ (x⁴)³ = x¹⁹/x¹² = x⁷

2)

$\frac{2 {}^{5} \times 3 {}^{9} }{2 {}^{3} \times 3 {}^{8} } = 2 {}^{2} \times 3 = 4 \times 3 = 12$

3)

x × 2¹³ = (2³)⁵

x × 2¹³ = 2¹⁵

2¹³x = 2¹⁵

8192x = 32768

x = 32768 : 8192

x = 4
