Question

calcule (+1\2) elevado a 2 . (5\3):(5\4) elevado a 2 = por favor me ajudem ?? urgente ?

Answer 1

Resposta:

${( \frac{1}{2} )}^{2} \times { (\frac{ \frac{5}{3} }{ \frac{5}{4} } )}^{2} = \\ \\ \frac{1}{4} \times ( { \frac{5}{3} \times \frac{4}{5} })^{2} = \\ \\ \frac{1}{4} \times ( { \frac{20}{15} })^{2} = \\ \\ \frac{1}{4} \times ( { \frac{4}{3} })^{2} = \frac{1}{4} \times \frac{16}{9} = \frac{16}{36} = \\ \\ \frac{4}{9}$

Answer 2

Resposta:

$( + \frac{1}{2} )^{2} \times ( \frac{5}{3} ) \div ( \frac{5}{4} )^{2} = \\ \\ \frac{1}{4} \times \frac{5}{3} \div \frac{25}{16} = \frac{1}{4} \times \frac{5}{3} \times \frac{16}{25} = \\ \\ \frac{1}{3} \times \frac{4}{5} = \frac{4}{15}$
