Question

Thực hiện các phép tính ; 27 .  ( 234 + 65 ) + 73 . ( 234 + 65 ) 

                                       2424 / 12 + 3636 / 12 

Answer 1

\(27.\left(234+65\right)+73.\left(234+65\right)\)

\(=\left(27+73\right).\left(234+65\right)\)

\(=100.299\)

\(=29900\)

\(\frac{2424}{12}+\frac{3636}{12}=\frac{2424+3636}{12}=\frac{6060}{12}=505\)

Answer 2

27 . (234+65) + 73 . (234+65) = (27+73) . (234+65) = 100. 299 = 29900

2424/12 + 3636/12 = (2424+3636)/12=6060/12=505
