Question

(2^2:4/3-1/2)•6/5-17

Answer 1

Lời giải:

\(\left(2^2:\dfrac{4}{3}-\dfrac{1}{2}\right).\dfrac{5}{6}-17\)

\(=\left(4:\dfrac{4}{3}-\dfrac{1}{2}\right).\dfrac{5}{6}-17\)

\(=\left(3-\dfrac{1}{2}\right).\dfrac{5}{6}-17\)

\(=\dfrac{5}{2}.\dfrac{5}{6}-17\)

\(=\dfrac{25}{12}-17=-\dfrac{179}{12}\)

Vậy ...

Answer 2

\(\)\(\left(\dfrac{2^2}{\dfrac{4}{3}}-\dfrac{1}{2}\right)\cdot\dfrac{6}{5}-17=\left(\dfrac{4}{\dfrac{4}{3}}-\dfrac{1}{2}\right)\cdot\dfrac{6}{5}-17=\left(3-\dfrac{1}{2}\right)\cdot\dfrac{6}{5}-17=\dfrac{5}{2}\cdot\dfrac{6}{5}-17=3-17=-14\)

Answer 3

Lời giải:

\(\left(2^2:\dfrac{4}{3}-\dfrac{1}{2}\right).\dfrac{6}{5}-17\)

\(=\left(4:\dfrac{4}{3}-\dfrac{1}{2}\right).\dfrac{6}{5}-17\)

\(=\left(3-\dfrac{1}{2}\right).\dfrac{6}{5}-17\)

\(=\dfrac{5}{2}.\dfrac{6}{5}-17\)

\(=3-17=-14\)
