The answer to your question is 2, 1/2, 1, 2

Step-by-step explanation:

a) 3² 4³ 2⁻¹ / (3 4)² = (3²)(4²) 4 (2⁻¹) / (3 4)² = (3  4)² 2² 2⁻¹ / (3  4)² = 2

b) 2⁴ 3⁵ / (2 3)⁵ = 2⁴ 3⁴ 3 / (2 3)⁵ = (2 3)⁴ 3 / (2 3)⁵ = 3 / 2 3 = 1/2

c) 3⁻³ 2⁻³ 6³ / (4°)² = (3 2)⁻³ 6³ / 1² = 6⁻³ 6³ = 1

d) (3 2)⁴ 3⁻³ / 2³3 = 3⁴2⁴ 3⁻³ / 2³3 = 3 2 / 3 = 2
