a) [ 316 – ( 25 . 4 + 16 )] : 8 – 24

Dài thế bro:)

chia ra

a/=-600000

b/=1200

c/-40

d/350

e/-508

:)

a) 600000

c) -40

e) 1922

b) -35

d) 350

a: \(2\cdot25\cdot4\cdot50\)

\(=\left(2\cdot50\right)\cdot\left(25\cdot4\right)\)

\(=100\cdot100=10000\)

b: \(\left(-125\right)\cdot5\cdot\left(-16\right)\cdot\left(-8\right)\)

\(=-125\cdot5\cdot16\cdot8\)

\(=-\left(125\cdot8\right)\cdot\left(5\cdot16\right)\)

\(=-80\cdot1000=-80000\)

c: \(5^2\cdot3^3\cdot2\)

\(=25\cdot27\cdot2\)

\(=\left(25\cdot2\right)\cdot27=27\cdot50=1350\)

d: \(\left(-4\right)\cdot3^2\left(-5\right)^3\)

\(=\left(-4\right)\cdot\left(-125\right)\cdot9\)

\(=500\cdot9=4500\)

a) 

=10000

b) 

=−80000

c) 

=27⋅50

=1350

d) 

=4500

ấn máy cho nhanh

đề ko yêu cầu tính nhanh mà ta, 

Thực hiện phép tính :

a) 46 - { [ ( 16 + 71 : 4 ) : 15 ] } - 2

= 46 - { [ ( 16 + 17,75 ) : 15 ] }

= 46 - { 33,75 : 15 }

= 46 - 2,25

= 43,75

b) 120 - { 300 : [ 150 - ( 2 . 5³ - 2³ . 25 ) ] }

= 120 - { 300 : [ 150 - (  2 . 5³ - 2³ . 5² ) ] }

= 120 - { 300 : [ 150 - (  2 . 5² ( 5 . 2² ) ] }

= 120 - { 300 : [ 150 - ( 50 . 20 ) ] }

= 120 - { 300 : [ 150 - 1000 ] }

= 120 - 300 : ( -850 )

= 120 + \(\frac{300}{850}\)

= \(\frac{10200}{850}\)+  \(\frac{300}{850}\)

= \(\frac{10500}{850}\)

= \(\frac{210}{17}\)

c) ( 20 . 24 + 12 . 24 - 4⁸ . 2² ) : 8²

= [ 24 . ( 20 + 12 ) - 4⁸ . 4 ] : 64

= ( 32 . 24 -  4⁹ ) : 64

= ( 768 - 4⁹ ) : 64

= 768 : 64 + 4⁹ : 64

= 12 + 4⁹ : 4³

= 12 + 4⁶

= 12 + 4096

= 4108

d) ( 75 . 5⁴ + 175 . 5⁴ ) : ( 20 . 25 . 125 - 625 . 75 )

= [ 5⁴  . ( 75 + 175 ) ] : ( 62500 - 625 . 75 )

= 5⁴ . 250 : 625 . ( 100 - 75 )

= 5² . ( 5² . 10 ) : 625 . 25

= 25 . 250 : 625 . 25

= 250

25x(8(12+4-8(16:8)))=25x(8x(16-8x2))=25x(8x(16-16)=25x(8x0)=25x0=0

Nhân chia trước cộng trừ sau , nên bn tự giải đi nha 

rối quá 

mik cho cách lm rồi đó tk mik nhé

a, 36:{336:[200–(12+8.20)]}

= 36:{336:[200–(12+160)]}

= 36:{336:[200–172]}

= 36:{336:28}

= 36:12 = 3

b, {145–[130–(246–236)]:2}.5

= {145–[130–10:2]}.5

= {145–130}.5

= 20.5 = 100

c, 100:{250:[450–(4. 5 3 – 2 2 .25]}

= 100:{250:[450–400]}

= 100:{250:50}

= 100:5 = 20

d, 798+100:[16–2.( 5 2 –22)]

= 798+100:10

= 798+10 = 808

e, (6954+1525:5+47.19).(29–58.2)

= (6954+1525:5+47.19).0 = 0

f,  2 4 .157– 2 4 .58+16

= 16.(157–58+1) = 1600

[ 316 - ( 25 x 4 + 16  ) ] : 8 - 24

= [ 316 - ( 100 + 16 ) ] : 8 - 24

= [ 316 - 116 ] : 8 - 24

=200 : 8 - 24

= 25 - 24

= 1

đúng rồi
