Answer 1

$3. lim_{x to -3} frac{(x+3)^2(x-1)^2}{x(x+3)(x+1)} =lim_{x to -3} frac{(x+3)(-3-1)^2}{-3(-3+1)}=0$

$4. lim_{x to -2} frac{ sqrt[3]{x-6} +2}{x+2} = lim_{x to -2} frac{ x-6+8}{(x+2)( sqrt[3]{(x-6)^2}-2 sqrt[3]{x-6}+4) } = frac{1}{4+4+4} = frac{1}{12}$

$5. lim_{x to 0} frac{x^2-2x}{tg(2 pi x+ pi )} =lim_{x to 0} frac{x^2-2x}{tg(2 pi x)} =lim_{x to 0} frac{x^2-2x}{2 pi x} = lim_{x to 0} frac{x-2}{2 pi } =\=- frac{1}{ pi }$
