2. Sederhanakan bentuk aljabar berikut ini.

a. (-y^5)/(-y^2)
= -y^(5-2)
= -y^3

b. (1/t)^7/(1/t)^3
= (1/t)^(7-3)
= (1/7)^4

c. (3m^7)/(m^3)
= 3m^(7-3)
= 3m^4

d. (42y^8)/(12y^5)
= (7/2)y^(8-5)
= (7/2)y^3

e. (1/t)^7 (1/t)^3
________ x _______
(1/t)^3 (1/t)^2

= (1/t)^(7-2)
= (1/t)^5

f. (3w^4)/(w^2) x 5w^3
= 3 x 5 x w^(4 - 2 + 3)
= 15w^5
