Question

Tính nhanh :

a/ 4x8x125x25

b/ 25+25x3

ai k mk mk k lại nha 

Answer 1

a) (4x25)x(8x125)=100x1000

=100000

b)(25+25)x3=50x3

=150

Answer 2

a/ 4x8x125x25

=(4x25)x(8x125)

=100x1000

=100000

ai k mk mk k lại nha

Answer 3

b/25+25x3

=25x1+25x3

=25x(1+3)

=25x4

=100

ai k mk mk k lại nhaa

Answer 4

a) (4*25)*(125*8)

=100*1000

=100000

b)(25+25)*3

=50*3

=150

Answer 5

a) 100000

b)100

Lại cho mik đi :)

Answer 6

4 x 8 x 125 x 25 

= ( 4 x 25 ) x ( 125 x 8 )

= 100 x 1000

= 100000

b) 25 + 25x 3 

= 25 x ( 1 + 3 ) 

= 25 x 4 

= 100

Answer 7

\(4\times8\times125\times25\)

\(=\left(4\times25\right)\times\left(8\times125\right)\)

\(=100\times1000\)

\(=100000\)

\(25+25\times3\)

\(=\left(25+25\right)\times3\)

\(=50\times3\)

\(=150\)

Answer 8

a, (4 x 25) x (8 x 125) = 100000

b: =25 x (1+3)

= 25 x 4 

=100

Answer 9

a / 4 x 8 x 125 x 25  = ( 4 x 25 ) x ( 8 x 125 ) 

                              = 100 x 1000

                              = 100000

b / 25 + 25 x 3 = 25 x ( 3 + 1 ) 

                      = 100

Answer 10

a) 4 x 8 x 125 x 25

 =( 4 x 25 ) x ( 8 x 125 )

 =  100      x    1000

=    100000

b) 25 + 25 x 3

 = 25 x 1 + 25 x 3

 =   25 x ( 1 + 3 )

 =  25  x    4

 =    100

Answer 11

a/ 4x8x125x25

=(4x25)x(8x125)

=100x1000

=100000

b/25+25x3

=(25+25)x3

=50x3

=150
