Question

Sederhanakan operasi berikut. a.4/2x + 5/x = b.2p/3a + p/4a = c.4p/5q - 2q/3p =

Answer 1

A. 4/2x + 5/x =
4(x) /(2x)(x) + 5(2x)/(2x)(x) =
4x+10x / 2x² =
14x /2x² = 7 / x (di bagi dengan 2x)

b. 2p/3a + p/4a =
2p(4a)/(3a)(4a) + p(3a)/(3a)(4a) =
8ap+3ap / 12a² =
11ap / 12a²

c. 4p/5q - 2q/3p =
4p(3p)/(5q)(3p) - 2q(5q)/(5q)(3p) =
12p²-10q² / 15pq
