Answer 2

Номер 501:
а)$sqrt{frac{1,44}{3,61}}= frac{1,2}{1,9}$
б)$sqrt{11frac{1}{9}}= sqrt{frac{100}{9}}= frac{10}{3}$
в)$sqrt{1 frac{13}{36}*3 frac{13}{36}}= sqrt{ frac{49}{36}* frac{121}{36}}= sqrt{ frac{49}{36}}* sqrt{ frac{121}{36}} = frac{7}{6}* frac{11}{6}= frac{77}{36}$
г)$sqrt{ frac{1}{144}* 2frac{12}{49}}= sqrt{ frac{1}{144}}* sqrt{ frac{100}{49}} = frac{1}{12}* frac{10}{7}= frac{10}{84}$
д)$sqrt{ frac{1}{9}*0,04*64 }= sqrt{ frac{1}{9}}* sqrt{ frac{4}{100}}* sqrt{64}= frac{1}{3}* frac{2}{10}*8= frac{16}{30}$
е)$sqrt{ 1frac{9}{16}* 2frac{1}{4}*2 frac{7}{9}}= sqrt{ frac{25}{16}}*  sqrt{frac{9}{4}}* sqrt{ frac{25}{9} }= frac{5}{4}* frac{3}2}* frac{5}{3}= frac{75}{24}$
Номер 503:
а)$sqrt{50*98}=5 sqrt{2}*7 sqrt{2}=35*2=70$
б)$sqrt{32*128}=4 sqrt{2}*8 sqrt{2}=32*2=64$
в)$sqrt{2,5*12,1}= sqrt{30,25}=5,5$
г)$sqrt{17*51*27}= sqrt{17}* sqrt{3}* sqrt{17}*3 sqrt{3}=17*3*3=153$
д)$sqrt{3,2*7,2*49}= sqrt{23,04}*7=48*7=336$
е-не получается
