A) 8xy²+2x / 4y
  = (2)³xy+2x / (2)²
  = 2xy + 2x

b) 5m²-5n² / m²-n²
  = 5m²-² - 5n²+²
  = 5(1) - 5n(pangkat4)

c) 24ab + 6b / 12ab² - 6a
  = 2 + 6b / ab - 6a

A. (2³xy²+2x) / 2²y
 = (2(2²xy²+x)) / 2²y
 = (2²xy+x) / 2y
 = (x(2²y+1)) / 2y

b. (5(m²-n²)) / (m²-n²)
 = 5

c. (6(4ab+b)) / (6(2ab²-a))
 = (4ab+b) / (2ab²-a)
