1) (16)^(3/4) x (9)^(3/2) = = (2^4)^(3/4) x (3^2)^(3/2) =(2)^ 4(3/4) x (3)^2(3/2) = 2^3 x 3^2 = 72 . 2) (27)^(2/3) x (625)^(3/4) / (81)^(1/2) = = (3)^3(2/3) x (5)^4(3/4) / (3)^4(1/2) = (3^2 x 5^3)/ (3^2) = 5^3= 125
(16)^(3/4) x (9)^(3/2) =
= (2^4)^(3/4) x (3^2)^(3/2)
=(2)^ 4(3/4) x (3)^2(3/2)
= 2^3 x 3^2
= 72
.
2)
(27)^(2/3) x (625)^(3/4) / (81)^(1/2) =
= (3)^3(2/3) x (5)^4(3/4) / (3)^4(1/2)
= (3^2 x 5^3)/ (3^2)
= 5^3= 125
