Решите 3xy/x-y*x-y/6xy^2 = (3ab^3/a-b) ^ (6ab^4) = (2a-b) ^2*2a+b/2a-b=

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.
