______ × ______
4 p

3. x x²+x
_____ ÷ ______
x-1 x²-1

4. 2m m²
________÷________
m²-16 m-4

tolong jawab !!!!

Answer 1

1) (5x/2y) x (3xy /x²) = 5/2 x 3/1 = 15/2

2) (p²+2p)/4 x p-2/p = p³ -4p/4p

3) (x/x-1) / (x²+x/x²-1) = (x/x-1) x (x² - 1/x² + x) = x/x²+x

4) (2m/m²-16) / (m²/m-4) = (2m/m²-16) x (m-4/m²) =( 2m/(m - 4)(m + 4)) x (m - 4/m²)
     2/m² + 4m
