Question

подробное решение пожалуйста​

Answer 1

lim(x->4) [✓1+2x - 3/✓x-2] = [ ✓1+2•4 - 3/✓4-2] = [✓9 - 3/✓2 ] = [3-3/✓2] = 0

Answer 2

$displaystyle tt lim_{x to 4} frac{sqrt{1+2x}-3}{sqrt{x-2}}=frac{sqrt{1+2cdot4}-3}{sqrt{4-2}}=frac{sqrt{9}-3}{sqrt{2}}=frac{3-3}{sqrt{2}}=frac{0}{sqrt{2}}=fbox{textbf{0}}$
