Ta có: \(B=\left(45\cdot1+912\right)\cdot37:\left(13\cdot74\right)\)

\(=\dfrac{37\left(45\cdot1+912\right)}{13\cdot74}\)

\(=\dfrac{45+912}{13\cdot2}\)

\(=\dfrac{957}{26}\)

45 x 11 mà?

(456x11+912)x37:13x74

= (5016+912)x37:13x74

=     5928      x37:13x74

=         219336    :13x74

=           16872         x74

=               1248528.

K nhé

\(\left(456\times11+912\right)\times37:13\times74\)

\(=\left(5016+912\right)\times37:13\times74\)

\(=5928\times37:13\times74\)

\(=219336:13\times74\)

\(=16872\times74\)

\(=1248528\)

=228 ban nhe k di

Tính :

( 456 x 11 + 912 ) x 37 : 13 : 74

= ( 456 x 11 + 456 x 2 ) x 37 : 13 : 74

= 456 x  ( 11 + 2 ) x 37 : 13 : 74

= 456 x 13 x 37 : 13 : 37 x 2

= 2³ x 3 x 19 x 13 x 37 : 13  : 37 x 2

= 8 x 3 x 19 x 37 : 37 x 2

= 4 x 3 x 19

= 228

Mk làm như vầy Không biết đã đúng hay chưa ? Mong các bạn giúp

\(\frac{\left(456.11+912\right).27}{13.74}\) đề như vậy hả?

( 456 .11+912 ) :13 :74=( 5016+912 ) :13 :74=5928:13:74=456:74=6,162

(456x11+912)x37:13:74

=(5016+912)x37:13:74

=5928x37:13:74

=219336:13:74

=16872:74

=228

(456x11+912)x37:13:74=(5016+912)x37:13:74=5928x37:13:74=219336:13:74=228

Mình củng đang thắc mắc .

   ( 456 x 11 + 912 ) x 37 : 13 x 74 

= ( 5 016 + 912 ) x 37 : 13 x 74

= 5 928 x 37 : 13 x 74 

= 219 336 : 13 x 74

= 16 872 x 74

= 1 248 528

=(5016+912). 37 : 13 : 74

=5928.37 : 13 : 74

=219336 : 13 : 74 

=16872:74

=2410

(456.11+912).37:13:74

= (456.11+912):13:(74:37)

= (456.11+456.2):13:2

= 456.(11+2):13:2

= 456.13:13:2

= (456:2).(13:13)

= 228.1

= 228
