Ta có: \(B=\left(45\cdot1+912\right)\cdot37:\left(13\cdot74\right)\)
\(=\dfrac{37\left(45\cdot1+912\right)}{13\cdot74}\)
\(=\dfrac{45+912}{13\cdot2}\)
\(=\dfrac{957}{26}\)
(456x11+912)x37:13x74
= (5016+912)x37:13x74
= 5928 x37:13x74
= 219336 :13x74
= 16872 x74
= 1248528.
K nhé
\(\left(456\times11+912\right)\times37:13\times74\)
\(=\left(5016+912\right)\times37:13\times74\)
\(=5928\times37:13\times74\)
\(=219336:13\times74\)
\(=16872\times74\)
\(=1248528\)
\(\frac{\left(456.11+912\right).37}{13.74}=\frac{\left(456.11+912\right).37}{13.37.2}=\frac{\left(456.11+456.2\right).37}{13.37.2}=\frac{456.\left(11+2\right).37}{13.37.2}\)
= \(\frac{456.13.37}{13.37.2}=\frac{456}{2}=228\)
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
( 456 .11+912 ) :13 :74=( 5016+912 ) :13 :74=5928:13:74=456:74=6,162

( 456 x 11 + 912 ) x 37 : 13 x 74
= ( 5 016 + 912 ) x 37 : 13 x 74
= 5 928 x 37 : 13 x 74

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