9900:36-15x11 ;    9700:100+36x12 ;   ( 15792 : 336 ) x 5 + 27 x 11

(160 x 5 – 25 x 4) : 4 ;   1036 + 64 x 52 – 1827 ;   215 x 86 + 215 x 14

12 054 : (15 + 67) ;   53 x 128 - 43 x 128 ;   29150 - 136 x 201

       các pác tính giá trị biểu thức giúp em nhá, em cẻm ơn

Answer 1

9900 : 36 - 15 x 11 

= 275 - 165

= 110

9700 : 100 + 36 x 12

= 97 + 432

= 529

 

( 15792 : 336 ) x 5 + 27 x 11

= 47 x 5 + 297

= 235 + 297

= 532

( 160 x 5 - 25 x 4 ) : 4

= ( 800 - 100 ) : 4

= 700 : 4

= 175

1036 + 64 x 52 - 1827

= 1036 + 3328 - 1827

= 4364 - 1827

= 2537

 

215 . 869 + 215 . 14 

= 215 . ( 869 + 14 ) 

= 215 . 883 

= 189945 

Answer 2

9900:36-15x11= 110 ;   

9700:100+36x12= 529 ;   

( 15792 : 336 ) x 5 + 27 x 11= 532

(160 x 5 – 25 x 4) : 4= 175

;   1036 + 64 x 52 – 1827 = 2537

   215 x 86 + 215 x 14= 21500

12 054 : (15 + 67) = 147

;   53 x 128 - 43 x 128 = 1280

;   29150 - 136 x 201= 1814

Answer 3

các pác trình bày tình bước ra giúp cháu cx đc ạ

Answer 4

9900:36-15x11=275-165=110

9700:100+36x12=97+432=529

(15792:336)x5+27x11=47x5+297=235+297=532

Answer 5

\(9900:36-15\times11=275-165=110\)

\(9700:100+36\times12=97+432=529\)

\(\left(15792:336\right)\times5+27\times11=47\times5+297=532\)

\(\left(160\times5-25\times4\right):4=\left(800-100\right):4=700:4=175\)

\(1036+64\times52-1827=1036+3328-1827=2537\)

\(215\times86+215\times14=215\times\left(86+14\right)=215\times100=21500\)

\(12054:\left(15+67\right)=12054:82=147\)

\(53\times128-43\times128=128\times\left(53-43\right)=128\times10=1280\)

\(29150-136\times201=29150-27336=1814\)

Answer 6

(160x5-25x4):4=(800-100):4=700:4=175

1036+64x52-1827=1036+3328-1827=2537

215x86+215x14=215x(86+14)=215x100=21500
