Question

Очень нужно решить!!!
Никак не могу.

Answer 1

$frac{48p^3q^4}{36p^2q^3} = frac{4pq}{3} \\ frac{x^2+6x+9}{x^2-9} = frac{(x+3)^2}{(x-3)(x+3)} = frac{x+3}{x-3}$


$frac{10x^2}{9y^2} = frac{40x^3}{36xy^2} \ frac{8}{12xy} =frac{24y}{36xy^2} \\ frac{b+2}{4b} = frac{b^2-4}{4b(b-2)} \ frac{4b+5}{4b-8} = frac{4b^2+5b}{4b(b-2)} \\ frac{2c}{c+d} = frac{2c(d-c)}{d^2-c^2} \ frac{3d}{d-c} = frac{3d(d+c)}{d^2-c^2} \\ frac{5t}{t^2-25} = frac{5t(t-5)}{(t-5)^2(t+5)} \ frac{t+5}{(t-5)^2}= frac{(t+5)^2}{(t-5)^2(t+5)}$
