3xy/x-y:6xy²/x-y

1) (3 * x * y)/(x - y) * (x - y)/(6 * x * y2) = ((3 * x * y) * (x - y))/((x - y) * (6 * x * y2)) = (3 * x * y)/(6 * x * y2) = 1/(2 * y);  

2) (3 * a * b3/a - b)(6ab^4) = (3 * a * b3)(6ab^4)/(a - b)(6ab^4);

3) (2 * a - b)2 * (2 * a + b)/(2 * a - b) = ((2 * a - b) * (2 * a - b) * (2 * a + b))/(2 * a - b) = ((2 * a - b) * (2 * a + b))/1 = (2 * a - b) * (2 * a + b) = (2 * a)2 - b2 = 4 * a2 - b2.
