32. Сократите дроби:

а) \(\dfrac{(y-4)(y+4)}{3(y+4)}=\boxed{\dfrac{y-4}{3}}\);

б) \(\dfrac{5(x-3y)}{(x-3y)(x+3y)}=\boxed{\dfrac{5}{x+3y}}\);

в) \(\dfrac{(c+2)^2}{7c(c+2)}=\boxed{\dfrac{c+2}{7c}}\);

г) \(\dfrac{6c(d-3)}{(d-3)^2}=\boxed{\dfrac{6c}{d-3}}\);

д) \(\dfrac{(a+5)^2}{(a-5)(a+5)}=\boxed{\dfrac{a+5}{a-5}}\);

е) \(\dfrac{3x(x+5y)}{x+5y}=\boxed{3x}\).
