Question

Tính giá trị biểu thức ( 427 × 54 + 427 + 427 ×45 ) : 5 =

Answer 1

(427 x 54 + 427 +427 x 45):5

= (427 x 54 + 427 x1 + 427 x 45): 5

=( 427 x ( 54+ 1 + 45)): 5

=( 427 x 100) : 5

= 42700: 5

=8540

Answer 2

( 427 × 54 + 427 + 427 ×45 ) : 5 = 427 (54 + 1 + 45)

                                                    = 427 . 100

                                                    = 42700

Answer 3

   ( 427 x 54 + 427+ 427 x 45 ) : 5

= [ 427x( 54+45+1) ] :5

= 427 x 100 :5

=   42700:5

=   8540 

Chúc em học tốt nha ^.^!

Answer 4

xin lỗi chưa chia :))

Answer 5

C1:(427 X 54 + 427 + 427X 45):5

    =(427 X 54+ 427 X 1+ 427 X 45 ):5

    =427X(54+1+45):5

     =427X100:5

      =42700:5

       =8540

C2:

(427 X 54 + 427 + 427X 45):5

    =(427 X 54+ 427 X 1+ 427 X 45 ):5

    =427X(54+1+45):5

     =427X100:5

     =427X(100:5)

     =427X20

     =8540

Answer 6

\(\left(427\times54+427+427\times45\right)\div5\)

\(=427\times\left(54+1+45\right)\div5\)

\(=427\times100\div5\)

\(=42700\div5\)

\(=8540\)

Answer 7

= 8540

Hk tốt,

k nehs

Answer 8

(427x54+427+427x45):5

=427x54+427+427x45x1:5

=427x(54+1+427+427):5

=427x      100               :5

=42700                         :5

=8540
