Question

помогите пожалуйста решить примеры

Answer 1

$a) sqrt{32} times sqrt{2} = sqrt{32 times 2} = sqrt{64} = 8$
$b) frac{ sqrt{300} }{ sqrt{3} } = sqrt{ frac{300}{3} } = sqrt{100} = 10$
$v) sqrt{19.6} = sqrt{ frac{196}{10} } = frac{14}{ sqrt{10} } = frac{14 sqrt{10} }{10} = frac{7 sqrt{10} }{5}$
$v) sqrt{19.6} times sqrt{0.4} = sqrt{196 times 0.1 times 4 times 0.1} = 14 times 0.1 times 2 = 2.8$
$g) sqrt{22.5} times sqrt{0.4} = sqrt{225 times 0.1 times 4 times 0.1} = 15 times 0.1 times 2 = 3$
$d) frac{ sqrt{15} }{ sqrt{240} } = sqrt{ frac{15}{240} } = sqrt{ frac{1}{16} } = frac{1}{4} = 0.25$
$e) frac{ sqrt{3.38} }{ sqrt{0.2} } = sqrt{ frac{3.38}{0.2} } = sqrt{ frac{33.8}{2} } = sqrt{16.9} = sqrt{ frac{169}{10} } = frac{13}{ sqrt{10} } = frac{13 sqrt{10} }{10}$
