Question

Сократите 2 дроби! !!!!!!!!!!!!!!!!!!!!

Answer 1

$frac{4 sqrt{x} -3 sqrt{y} }{9y-16x} = frac{4 sqrt{x} -3 sqrt{y} }{(3 sqrt{y}-4 sqrt{x})(4 sqrt{x}+3 sqrt{y})} = -frac{1}{4 sqrt{x}+3 sqrt{y}}$

$frac{6 sqrt{ab} -9 sqrt{c} }{81c-36ab} = frac{6 sqrt{ab} -9 sqrt{c} }{(9 sqrt{c}-6 sqrt{ab})(6 sqrt{ab} +9 sqrt{c})} =- frac{1}{6 sqrt{ab} +9 sqrt{c}}$

Answer 2

(4sqrt(x)-3sqrt(y))/(3sqrt(y)+4sqrt(x))(3sqrt(y)-4sqrt(x))=-1/(3sqrt(y)+4sqrt(x))
2)
(6sqrt(ab)-9sqrt(c))/(9sqrt(c)+6sqrt(ab))(9sqrt(c)-6sqrt(ab))=-1/(6sqrt(ab)+9sqrt(c))
