Question

Como eu calculo essas expressões?
√16/25 + √1/100 : √16/25 + √1/100 : √25/36
B)√0.5 - 0.14 : 0.25

Answer 1

Resposta:

$1:\sqrt{\dfrac{25}{36}} =\\\\\\1:\dfrac{5}{6} =\dfrac{6}{5}$

Explicação passo-a-passo:

Vamos lá!

• Você pode simplificar essas frações e fica o resultado sendo 6/5.

$1:\sqrt{\dfrac{25}{36}} =\\\\\\1:\dfrac{5}{6} =\dfrac{6}{5}$

Tirando a prova, temos:

$\dfrac{\sqrt{\dfrac{16}{25} } + \sqrt{\dfrac{1}{100} } }{\sqrt{\dfrac{16}{25} } + \sqrt{\dfrac{1}{100} } } :\sqrt{\dfrac{25}{36} }= \\\\\\\dfrac{{\dfrac{4}{5} } + {\dfrac{1}{10} } }{{\dfrac{4}{5} } + {\dfrac{1}{10} } } :{\dfrac{5}{6} }=\\\\\\\dfrac{{\dfrac{8+1}{10} } }{{\dfrac{8+1}{10} } } :{\dfrac{5}{6} }=\\\\\\\dfrac{{{9.10} } }{{{10.9} } } :{\dfrac{5}{6} }=\\\\\\\dfrac{{{90} } }{{90 } } :{\dfrac{5}{6} }=\\\\\\1 :{\dfrac{5}{6} }=\\\\\dfrac{6}{5}$
