\(\text{364 * 75 - 278 * 78 + 25 * 364 - 278 * 22}\)
\(=364.\left(75+25\right)+278.\left(-78-22\right)\)
\(=364.100+278.\left(-100\right)\)
\(=36400+\left(-27800\right)\)
\(=8600\)
364x75-278x78+25x364-278x22
=364x(75+25)-278x(78+22)
=364x100-278x100
=100x(364-278)
=100x86
=8600
364.75-278.78+25.364-278.22
=364.(75+25)-278.(78+22)
=364.100-278.100
=36400-27800
=8600
364 x 75 - 278 x 78 + 25 x 364 - 278 x 22
=
(364.75+25.364)-(278.78+278.22)
= 364(75+25) - 278(78+22)
= 364.100-278.100
=100(364-278)
=100. 86
=8600
Chúc bạn học tốt !
nguyễn ngọc linh bạn làm sai r.
=364 x278 - (75+25)+(78+22)
=364x278 - (100+100)
=364x278 - 200
=364x78
=20592
