nói chung là lên gg mà sợt;vvv
Tính nhanh:
a) 13 . 58 . 4 + 32 .26 . + 52 . 10
b) 53. 51 + 4 + 53 . 49 + 91 + 53
Mình đang cần gấp, bạn nào giúp mình thì mình cảm ơn nhiều nha
a) 13 . 58 . 4 + 32 . 26 . 2 + 52 . 10 b) 53 . 51 + 4 + 53 . 49 + 91 + 53
= 52 . 58 + 32 . 52 + 52 . 10 = 53 . 55 + 53 . 145 + 53 . 1
= 52. ( 58 + 32 + 10 ) = 53 . ( 55 + 145 + 1 )
= 52 . 100 = 53 . 201
= 52000 = 10653
~ Chúc bn hok tốt ~
53. ( 51 + 4 ) + 53. ( 49 + 96 ) + 53 =?
53.51+51.4+ 53.49+ 53.96+53
= 53.(51+49)+ 53.( 96+4)+ 53
= 53.100+ 53. 100 + 53
= 5300+5300+53
=10600+53
=10653
****
53.{51+4}+53.{49+96}+53
\(53\cdot\left(51+4\right)+53\cdot\left(49+96\right)+53\)
=\(53\cdot55+53\cdot145+53\cdot1\)
=\(53\cdot\left(55+145+1\right)\)
=\(53\cdot201\)
=10653
nếu Đ thì k cho mk nhá
Tính nhanh:
53 (51 + 4) + 53 (49 + 96) + 53
53 x (51+4) +53 x (49+96) +53
=53×55+53x145+53×1
=53×(55+145+1)
=53×201
=10653
chúc bạn học tốt
= 53 x ( 51 + 4 + 49 + 96 +1 )
= 53 x 201
= 10653
\(53\left(51+4\right)+53\left(49+96\right)+53\)
\(=53.55+53.145+53.1\)
