help pls

(451 x 13 + 9 x 13) x 37/13 x 74
= 13 x (451 + 9) x 37/13 x 74
= 13 x 460 x 37/13 x 74
= (13 x 37/13) x (460 x 74)
= 37 x 34040
= 1259480

(456x11+912)x37:13x74

K nhé

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

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

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

\(=219336:13\times74\)

\(=16872\times74\)

\(=1248528\)

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

2010 x 2010 - 2009 x 2011

= ( 2011 - 2010 ) x 2010 - 2009 x 2011

= 2011 x 2010 - 1 x 2010 - 2009 x 2011

= 2011 x ( 2010 - 2009 ) - 1 x 2010

= 2011 x 1 - 2010 

= 2011 - 2010 

= 1

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

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

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

= [ 456 x 13 ] x 37 : ( 13 x 74 )

= 13 x 456 x 37 : ( 13 x 37 x 2 )

= 13 x 37 x 2 x 228 : ( 13 x 37 x 2 )

= ( 13 x 37 x 2 ) x 228 : ( 13 x 37 x 2 )

= ( 13 x 37 x 2 ) : ( 13 x 37 x 2 ) x 228

= 1 x 228

= 228

(44 x 52 x 60) : (11 x13 x 15 )

= [ ( 4 x 11 ) x ( 4 x 13 ) x ( 4 x 15 ) ] : (11 x13 x 15 )

= [ 4 x 11 x 4 x 13 x 4 x 15 ] : (11 x13 x 15 )

= [ ( 4 x 4 x 4 ) x ( 11 x 13 x 15 ) ] : (11 x13 x 15 )

= 64 x (11 x13 x 15 ) : (11 x13 x 15 )

= 64 x 1

= 64

a) 2010 x 2010 - 2009 x 2011 

= 2010 x 2010 - [ 2009 x ( 2010 +1) ]

=2010 x 2010 - 2009 x 2010 - 2009 

=2010( 2010 - 2009 ) -2009 

= 2010 -2019

= 1

c) ( 44 x 52 x60 ) : (11x13x15)

\(\frac{44\cdot52\cdot60}{11\cdot13\cdot15}=\frac{4\cdot11\cdot4\cdot13\cdot4\cdot15}{11\cdot13\cdot15}=64\)

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

= \(\frac{\left(456\cdot11+912\right)\cdot37}{13\cdot74}=\frac{\left[456\left(11+2\right)\right]\cdot37}{13\cdot37}=\frac{456\cdot13}{13\cdot2}=\frac{456}{2}=228\)

Nhớ k mik nha bn

( 456 x 11 + 912 ) x 37 : 13 x 74 = 1248528

ko được dùng máy tính đâu bạn

Tìm y biết
