rozwiązania:
\sqrt{49} +3 \sqrt{16}-( \sqrt{25}) ^{2}=7+3*4-25=19-25=-6
6* \sqrt{121} -( \sqrt{7}) ^{2}=6*11-7=66-7=59
\sqrt{25-9} *(-2)=\sqrt{16}*(-2)=4*(-2)=-8
\sqrt[3]{131- \sqrt{36} }=\sqrt[3]{131-6}=\sqrt[3]{125}=5
\sqrt{38- \sqrt[3]{8} }=\sqrt{38-2}=\sqrt{36}=6
\sqrt[3]{384: \sqrt{36} }=\sqrt[3]{384:6}=\sqrt[3]{64}=4
\sqrt{270* \sqrt{225* \sqrt{16} }}=\sqrt{270*\sqrt{225*4}}=\sqrt{270*\sqrt{900}}=\sqrt{270*30}=\sqrt{8100}=90
\sqrt{110+ \sqrt{121} }=\sqrt{110+11}=\sqrt{121}=11
\sqrt{200+ \sqrt{625} }=\sqrt{200+25}=\sqrt{225}=15
