Question

Tính nhanh: 265 _^x 236 + 265 x 265 - 265

Answer 1

= 132500

Answer 2

\(265\times236+265\times265-265\)

\(=265\times\left(236+265-1\right)\)

\(=265\times500\)

\(=132500\)

Answer 3

265 x 236 + 265 x 265 - 265

= 265 x 236 + 265 x 265 - 265 x 1

= 265 x (236 + 265 - 1)

= 265 x 500

= 13250
