nói chung là lên gg mà sợt;vvv

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 ~

câu b có đúng ko vậyNguyễn Thanh Vân

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

****

10600

\(53\cdot\left(51+4\right)+53\cdot\left(49+96\right)+53\)

=\(53\cdot55+53\cdot145+53\cdot1\)

=\(53\cdot\left(55+145+1\right)\)

=\(53\cdot201\)

=10653

nếu Đ thì k cho mk nhá

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
 

\(53\left(51+4\right)+53\left(49+96\right)+53\)

\(=53.55+53.145+53.1\)

\(=53.\left(55+145+1\right)\)

\(=53.201\)

\(=10653\)
