Приведите дроби к общему знаменателю:

1) 5a/a^3-27 , a-3/a^2+3a+9 и 1/a-3

2) 3/x+2 , X+1/X^3+8 и X+2/X^2-2X+4

1) $\frac{5a}{a^3-27}=\frac{5a}{(a-3)(a^2+3a+9)}$

$\frac{(a-3)}{a^2+3a+9}=\frac{(a-3)^2}{(a-3)(a^2+3a+9)}$

$\frac{1}{a-3}=\frac{a^2+3a+9}{(a-3)(a^2+3a+9)}$

2) $\frac{3}{x+2}=\frac{3(x^2-2x+4)}{(x+2)(x^2-2x+4)}$

$\frac{x+1}{x^3+8}=\frac{x+1}{(x+2)(x^2-2x+4)}$

$\frac{x+2}{x^2-2x+4}=\frac{(x+2)^2}{(x+2)(x^2-2x+4)}$
