Question

вычисление предела, помогите пожалуйста

Answer 1

$5. lim_{x to 2} frac{5(x-2)^2}{(x-2)(x^2+2x+4)} = lim_{x to 2} frac{5(x-2)}{x^2+2x+4} =0$

$6. lim_{x to 3} frac{ sqrt{2x+10} -4}{x-3} = lim_{x to 3} frac{ frac{1}{ sqrt{2x+10}} }{1}= frac{1}{ sqrt{16} } =0,25$

$7. lim_{x to 0} frac{sin17x}{x} =lim_{x to 0} frac{17cos17x}{1} =17$
