Answer 1

Answer:

Step-by-step explanation:

===============

x × (2/5)⁴= 25

x= 25/ (2/5)⁴

x=5²/2⁴/5⁴=

x=5²⁺⁴/2⁴

x=5⁶/2⁴

===============

Product of the cube of (-2/3) and the square of (4/-5)

(-2/3)³ ×  (4/-5)² =

-2³/3³ ×  4²/5²=

-2³/3³ ×  2⁴/5²=

-2³⁺⁴/3³5²=

-2⁷/3³5²

===============

a)

(4/5)⁻⁴ × (6)⁻⁴=

(2²/5)⁻⁴ × (2×3)⁻⁴=

2⁻⁸/5⁻⁴× 2⁻⁴×3⁻⁴=

2⁻⁸⁻⁴×3⁻⁴/5⁻⁴=

2⁻¹²×(3/5)⁻⁴

b)

(-3)⁻⁸ × (-1/9)⁻⁸=

3⁻⁸ × (1/9)⁻⁸=

3⁻⁸ × 9⁸=

3⁻⁸ × 3¹⁶=

3⁻⁸⁺¹⁶=3⁸
