Question

tính:

      9x8+109x65-87x23+12x12-33x6

Answer 1

\(9\cdot8+109\cdot65-87\cdot23+12\cdot12-33\cdot6\)

\(=72+7084-2001+144-198\)

\(=7156-2001+144-198\)

\(=5155+144-198\)

\(=5299-198\)

\(=5101\)

Answer 2

= 72 + 7084 - 2001 + 144 - 198

= 7156 - 2001 + 144 - 198

= 5155 + 144 - 198

= 5299 - 198

= 5101
