Question

Помогите пожалуйста решить:

Answer 1

$frac{3}{4} sqrt{0.64} - frac{2}{7} sqrt{24.01} + sqrt{46.24} = frac{3}{4}cdot 0.8-frac{2}{7}cdot4.9+ 6.8=8.8$

$0.8 sqrt{54.76} + frac{9}{10} sqrt{2.25}- sqrt{79.21} =0.8cdot 7.4+frac{9}{10}cdot 1.5-8.9=-1.63$

$-38 sqrt{ frac{90.25}{361} } +11 sqrt{ frac{225}{484} }+0.5 sqrt{7744} =-38cdot 2+11cdot frac{15}{22} +44=-24.5$

$48 sqrt{ frac{49}{256} } - frac{26}{3} sqrt{ frac{900}{169} } +62 sqrt{ frac{144}{961} } =48cdot frac{7}{16} - frac{26}{3} cdot frac{30}{13} +62cdot frac{12}{31} =25$
