Question

( 1 / 3 )2 + √ 25 / 36 - [ ( -2 / 3 )2 + 2 / 3 x 1 / 4 ] quem souber pfv fala antes de 17 hrs :(

Answer 1

$( \frac{1}3{} )^{2} + \frac{ \sqrt{25} }{36} -[( \frac{ - 2}{3} ) ^{2} + \frac{2}{3} \times \frac{1}{4}] \\ \\ \frac{1}{9} + \frac{5}{36} - [ \: \: \frac{4}{9} + \frac{2}{12} ] \\ \\ \frac{4 + 5}{36} - \: ( \frac{16 + 6}{36} ) \\ \\ \frac{9}{36} - \frac{22}{36} \\ \\\boxed{{\sf\color{orange}{ \frac{ - 13}{36} } {}}}$

espero ter ajudado!
