Question

A = \(\left(-\dfrac{2}{3}\right)^2+\left(-\dfrac{7}{8}\right)+\left(-\dfrac{11}{12}\right)\)

Answer 1

A= \(\dfrac{4}{9}+\left(\dfrac{-7}{8}\right)+\left(\dfrac{-11}{12}\right)\)

A= \(\dfrac{32}{72}+\left(\dfrac{-63}{72}\right)+\left(\dfrac{-66}{72}\right)\)

A= \(\left(\dfrac{-31}{72}\right)+\left(\dfrac{-66}{72}\right)\)

A= \(\dfrac{-97}{72}\)

Tick mk nha!

Answer 2

\(A=\dfrac{4}{9}+\left(\dfrac{-7}{8}\right)+\left(\dfrac{-11}{12}\right)\)

\(=\dfrac{32}{72}+\left(\dfrac{-63}{72}\right)+\left(\dfrac{-66}{72}\right)\)

\(=\left(\dfrac{-31}{72}\right)+\left(\dfrac{-66}{72}\right)\)

\(=\dfrac{-97}{72}\)
