123,45x135-123,45x36+123,45

Answer 1

123,45 x 135 - 123,45 x 36 + 123,45 = 123,45 x 135 - 123,45 x 36 + 123,45 x 1 

                                                           = 123,45 x ( 135 - 36 + 1 )

                                                           = 123,45 x 100

                                                           = 12345

Answer 2

123,45 x 135 - 123,45 x 36 + 123,45 

= 123,45 x ( 135 - 36 + 1 )

= 123,45 x 100

= 12345

Answer 3

\(123,45.135-123,45.36.123,45\)

\(=123,45.\left(135-36+1\right)\)

\(=123,45.100\)

\(=12345\)

Answer 4

123,45 x 135 - 123,45 x 36 + 123,45

= 123,45 x (135 - 36 + 1)

= 123,45 x 100

= 12345

Answer 5

123,45 x 135 - 123,45 x 36 + 123,45

= 123,45 x ( 135 - 36 + 1 )

= 123,45 x 100

= 12345

.........

Answer 6

123,45x135-123,45x36+123,45

=123,45x(135-36+1)

=123,45x100

=12345

Answer 7

\(123,45\times135-123,45\times36+123,45\)

\(=123,45\times(135-36+1)\)

\(=123,45\times100\)

\(=12345\)

Answer 8

\(123.45\)X \(135-123.45\)X \(36+123.45=123.45\)X  \(135-123.45\)X \(36+123.45\)X \(1\)

\(=123.45\)X \(\left(135-36+1\right)\)

\(=123.45\)X \(100\)

\(=12345\)

Answer 9

Trả lời:

\(123,45\cdot135-123,45\cdot36+123,45\)

\(=123,45\cdot\left(135-36+1\right)\)

\(=123,45\cdot100\)

\(=12345\)
