Explicație pas cu pas:

$\sqrt{14^{2}}=14;~\sqrt{23^{4} }=\sqrt{(23^{2})^{2}}=23^{2};~\sqrt{(-35)^{2}}=|35|=35;~\sqrt{3^{6}}=\sqrt{(3^{3})^{2}}=3^{3};~\sqrt{(-7)^{4}}=\sqrt{7^{4}}=\sqrt{(7^{2})^{2}}=7^{2};~\sqrt{a^{2}}=|a|;~\sqrt{a^{4}}=\sqrt{(a^{2})^{2}}=a^{2};~\sqrt{(-a)^{8}}=\sqrt{a^{8}}=\sqrt{(a^{4})^{2}}=a^{4};~\sqrt{a^{6}}=\sqrt{(a^{3})^{2}}=|a^{3}|=|a|^{3}.\\ \sqrt{2^{4}*3^{2}}=2^{2}*3=12;~\sqrt{16^{2}*5^{2}}=16*5=80;~\sqrt{2^{2}*3^{2}*5^{2}}=2*3*5=30;~\sqrt{2^{6}*5^{2}*3^{4}}=2^{3}*5*3^{2};~\sqrt{18^{2}*3^{4}*3^{6}}=$$18*9*27;~\sqrt{12^{2}*3^{4}*5^{2}}=12*9*5.$
