16*(27+75)+8*(53+45)*2=3200
học tốt
nhé bạn
=16*(102+98)
=16*200
=3200
study well
k nha
ai k đúng cho mk mk trả lại gấp đôi
\(16.\left(27+75\right)+8.\left(53+45\right).2\)
\(=16.102+8.98.2\)
\(=16.102+16.98\)
\(=16.\left(102+98\right)\)
\(=16.200\)
\(=3200\)
HOK TOT
16 ( 27 + 75 ) + 8 ( 53 + 45 ) . 2
= 16 ( 27 + 75 ) + 16 ( 53 + 45 )
= 16 ( 27 + 75 + 53 + 45 )
= 16 . 200
= 3 200
=))
làm thế này
16 * ( 27 +75 ) + 8 * ( 53 + 45 ) * 2
= 16 * 102 + 8 * 98 * 2
= 16 * 102 + ( 8* 2 ) * 98
=16 * 102 + 16 * 98
= 16 * ( 102 + 98 )
= 16 * 200
= 3200
\(16\text{ x }\left(27+75\right)+8\text{ x }\left(53\text{ x }45\right)\text{ x }2\)
\(=16\text{ x }100+8\text{ x }2\text{ x }\left(53+45\right)\)
\(=16\text{ x }100+16\text{ x }98\)
\(=16\text{ x }\left(100+98\right)\)
\(=16\text{ x }198\)
\(=3168\)
Trả lời :
16 . 102 + 8 . 98 .2
= 1632 + 1568
= 3200
Study well :>
16 . 102 + 8 . 98 . 2
= 1632 + 1568
= 3200
Hc tốt
Sorry mình tính nhầm ! Làm lại
\(16\text{ x }(27+75)+8\text{ x }(53+45)\text{ x }2\)
\(=16\text{ x }102+8\text{ x }2\text{ x }\left(53+45\right)\)
\(=16\text{ x }102+16\text{ x }98\)
\(=16\text{ x }\left(102+98\right)\)
\(=16\text{ x }200\)
\(=3200\)
\(16\text{ x }(27+75)+8\text{ x }(53+45)\text{ x }2\)
\(=16\text{ x }102+8\text{ x }2\text{ x }\left(53+45\right)\)
\(=16\text{ x }102+16\text{ x }98\)
\(=16\text{ x }\left(102+98\right)\)
\(=16\text{ x }200\)
\(=3200\)
\(16.\left(27+75\right)+8.\left(53+45\right).2\)
\(=16.102+8.98.2\)
\(=16.102+16.98\)
\(=16.\left(102+98\right)\)
\(=16.200\)
\(=3200\)
Giống tính nhanh ko nhỉ ???
