(4³*16⁴ : 5√32)/(64 ^-¾ *8^ 5/3) = [(2²)³ * (2⁴)⁴ : (2⁵)^5/2]/[(2⁶)^-¾ * (2³)^5/3] = [2⁶ * 2¹⁶ : (2^25/2)]/(2^-9/2)*2⁵ = (2^19/2)/ 2^1/2 = 2⁹ = 512

(5^2/3 * 125^- 5/3 : 4√625²)/4 * 5 ^¾ + 5^ ¾ = [(5^2/3 * (5³)^ -5/3:(5⁴)^1/4]/5 * 5 ^¾ = (5^2/3 *5⁻⁵: 5)/(5^7/4) = (5^-16/3)/(5^7/4) = (5^-64/12)/(5^21/12) = 5^-75/12
