Answer 1

$(10^{6}) = 1.000.000\\(\sqrt{16}) = \sqrt4^{2} : 2 = 4\\(0,3*100)=0,3*10^{2} =3*10^{1} \\(1,9*10)=19\\(\sqrt{64})=\sqrt 8^2}: 2 = 8\\(2*5+\sqrt{100})=10+\sqrt{100}=10+10=20\\(\sqrt{49})=\sqrt{7}^{2}:2= 7\\(2^{3}+2)=8+2=10\\(5^{2}+2^{5}+4^{2})=25+32+16=73\\(7,25+6,23)=13,48\\(5*10^{2})=5*100=500\\(6^{2}+3*\sqrt{81}+\sqrt{25})=36+3*9+5=36+27+5= 68\\(2*\sqrt{25})=2*5=10\\(2*\sqrt{100})=2*10=20\\(2*6^{2}-7)=2*36-7=72-7=65\\(5*\sqrt{4})=5*2=10\\(\sqrt{9})=\sqrt{3}^2:2=3$
