Question

1 phần 10 - (1 phần 3) mũ 2 : 5 phần 9

Answer 1

   \(\dfrac{1}{10}-\left(\dfrac{1}{3}\right)^2:\dfrac{5}{9}\)

= \(\dfrac{1}{10}-\dfrac{1}{9}:\dfrac{5}{9}\)

= \(\dfrac{1}{10}-\dfrac{1}{9}.\dfrac{9}{5}\)

= \(\dfrac{1}{10}-\dfrac{1}{5}\)

= \(\dfrac{1}{10}-\dfrac{2}{10}\)

= \(-\dfrac{1}{10}\)

 

Answer 2

\(\dfrac{1}{10}-\left(\dfrac{1}{3}\right)^2:\dfrac{5}{9}\)

=\(\dfrac{1}{10}-\dfrac{1}{9}:\dfrac{5}{9}\)

=\(\dfrac{1}{10}-\dfrac{1}{9}.\dfrac{9}{5}\)

=\(\dfrac{1}{10}-\dfrac{1}{5}\)

=\(\dfrac{1}{10}-\dfrac{2}{10}\)

=\(\dfrac{-1}{10}\)=-0.1

Answer 3

Ta có: \(\dfrac{1}{10}-\left(\dfrac{1}{3}\right)^2:\dfrac{5}{9}\)

\(=\dfrac{1}{10}-\dfrac{1}{9}:\dfrac{5}{9}\)

\(=\dfrac{1}{10}-\dfrac{1}{9}\cdot\dfrac{9}{5}\)

\(=\dfrac{1}{10}-\dfrac{1}{5}\)

\(=\dfrac{1}{10}-\dfrac{2}{10}\)

\(=-\dfrac{1}{10}\)
