tolong dongg ga ngerti tolong jawab yaaa.. yang a, g, dan h doang kok:)

a) 8²/⁹ x 8⁴/⁹ = (2³)²/⁹ x (2³)⁴/⁹ = 2²/³ x 2⁴/³ = 2²/³⁺⁴/³ = 2² = 4

g) 64¹/² : 64⁷/⁶ = (2⁶)¹/² : (2⁶)⁷/⁶ = 2³ x 2⁷ = 2³⁺⁷ = 2¹⁰

h) 81⁻¹/² : 81⁻³/⁴ = (3⁴)⁻¹/² : (3⁴)⁻³/⁴ = 3⁻² : 3⁻³ = 3⁻²⁻⁽⁻³⁾ = 3¹ = 3

semoga jelas dan membantu ya
