Помогите сделать упражнение 37 (первые 6 задач)

Answer 1

$1) 20*sqrt{6.25}+frac1{39}*sqrt{169}=20*2.5+frac{13}{39}=50+3=53\ \ 2)15*sqrt{0.16}-frac{5}{58}sqrt{841}=15*0.4-frac{29}{58}=6-0.5=5.5\ \ 3)frac5{sqrt{400}}-0.8sqrt{1.44}=frac5{20}-0.8*1.2=0.25-0.96=-0.71\ \ 4)0.36sqrt{0.36}-3.5sqrt{0.09}=0.36*0.6-3.5*0.3=0.216-1.05=\=-0.834\ \ 5)(5sqrt{11})^2=25*11275\ \ 6)(3sqrt{13})^2=9*13=117$
