Sederhanakan a. 3^3 x 3^-1 : 3^5 x 3^2 b. 5^2 x (1/123) ^-1 : 25^2 c. (4^2 x 2^-4) x (5^2 x 3^-2)^2

a. 3³×3⁻¹/3⁵×3²
= 3³⁻¹/3⁵⁺² = 3⁴/3⁷ = 3⁴⁻⁷ = 3⁻³

b. 5²×(1/123)⁻¹/25² = 5²×123/(5²)² = 5²×123/5⁴ = 5²⁻⁴×123 = 5⁻²×123

c. (4²×2⁻⁴)×(5²×3⁻²)² = ((2²)²×2⁻⁴)×(5²*²×3⁻²*²) = (2⁴×2⁻⁴)×(5⁴×3⁻⁴) = (5⁴×3⁻⁴)
