Question

вычислите квадрат числа 1/4 3/8 5/6 2/7 1 1/2 4 1/9 6 2/3

Answer 1

$( frac{1}{4} )^{2} = frac{1}{16} ; ( frac{3}{8}) ^{2} = frac{9}{64}; ( frac{5}{6}) ^{2} = frac{25}{36}; (frac{2}{7} )^{2} = frac{4}{49};$

$(1frac{1}{2} )^{2} = (frac{3}{2} )^{2} =frac{9}{4}=2frac{1}{4};(4frac{1}{9} )^{2} = (frac{37}{4} )^{2} =frac{1369}{16}=85frac{9}{16};$
$(6frac{2}{3} )^{2} = (frac{20}{3} )^{2} =frac{400}{9}=44frac{4}{9}$
