Explicație pas cu pas:

$1.~\sqrt{64}=8\\2.~\sqrt{4}+\sqrt{121}=2+11=13\\3.~\sqrt{0,49}+\sqrt{1,69}=0,7+1,3=2\\4.~\sqrt{\frac{1}{4} }+ \sqrt{\frac{1}{9} }+\sqrt{\frac{49}{36} }=\frac{1}{2}+ \frac{1}{3}+\frac{7}{6}=\frac{3}{6}+\frac{2}{6}+\frac{7}{6}=\frac{12}{6}=2.\\5.~\sqrt{(-35)^{2}}=|-35|=35.~~Am~aplicat~formula~\sqrt{x^{2}}=|x|$
