Question

[ (2/3²)] - (√36/16 ÷ 5/3 . 2/4) ]

Answer 1

Explicação passo-a-passo:

$( \frac{2}{3 {}^{2} } ) - ( \frac{ \sqrt{36} }{16} ) \div \frac{5}{3} . \frac{2}{4} = \frac{2}{9} - ( \frac{6}{16} \div \frac{5}{3} . \frac{2}{4} ) =$

$\frac{2}{9} - ( \frac{6}{16} \times \frac{3}{5} \times \frac{2}{4} ) = \frac{2}{9} - ( \frac{36}{320} ) = \frac{2}{9 } - \frac{18}{160} = \frac{2}{9} - \frac{9}{80} = \frac{160 - 81}{720} = \frac{79}{720}$

Answer 2

Resposta:

-1/180

Explicação passo a passo:

[ (2/3²)] - (√36/16 ÷ 5/3 . 2/4) ]

[4/9] - (6/4 ÷ 5/3 . 2/4)]

[4/9] - (6/4 * 3/5 . 2/4)]

[4/9] - (18/20 . 2/4)]

[4/9] - (36/80)]

4/9 - 36/80

(320 - 324)/720

-4/720

-1/180
