3.7x3.8+8.3x3.7-0.4x3.7x5=1523.142

cho mình nha

=3,7*(3,8+8,3-0,4*5) = 3,7*10,1=37,37

= 37.37

0.25 x 4 x 3.6 : 0.125=1x3,6x1:8=0,45

5.79 x 0.24 - 0.12 x 1.58=0,24x5=1,2

nhớ k mình nhé

\(9,5\times3,7+9,5\times1,3+9,5:0,25+9,5\)

\(=9,5\times3,7+9,5\times1,3+9,5\times4+9,5\)

\(=9,5\times\left(3,7+1,3+4+1\right)\)

\(=9,5\times10\)

\(=95\)

a, 96 x 123,47 + 123,47 :0,25

=96 x 123,47 + 123, x 4

=123,47 x ( 96 + 4 )

=123,47 x 100

= 12347

b, 1008 x 2,015 + 2,015 : 0,125

=1008 x 2,015 + 2,015 x 8

=2,015 x ( 1008 + 8 )

=2,015 x 1016

=2047,24

a 96 x 123.47 + 123.47 : 0,25

=96 x 123.47 + 123.47 x 4

=(96 + 4) x 123.47

=100 x 123.47

= 12347
