Question

4/3 x 13/3 - 4/3 x 40/9

ghi rõ cách giải giùm nha.

Answer 1

4/3 x (13/3 - 40/9)

4/3 x (39/9 - 40/9)

4/3 x (-1/9) = -4/27

Answer 2

\(\frac{4}{3}x\frac{13}{3}-\frac{4}{3}x\frac{40}{9}=\frac{4x13}{3x3}-\frac{4x40}{3x9}=\frac{52}{9}-\frac{80}{27}=\frac{516}{27}-\frac{80}{27}=\frac{436}{27}\)

Answer 3

\(\frac{4}{3}\times\frac{13}{3}-\frac{4}{3}\times\frac{40}{9}\)

\(=\frac{4}{3}\times\left(\frac{13}{3}-\frac{40}{9}\right)\)

\(=\frac{4}{3}\times\left(\frac{-1}{9}\right)\)

\(=\frac{-4}{27}\)
