20,11x36+63x20,11+20,11

Answer 1

\(20,11\times36+63\times20,11+20,11\)

\(=20,11\times\left(36+63+1\right)\)

\(=20,11\times100\)

\(=2011\)

Answer 2

20,11x36+63x20,11+20,11

=20,11x(36+63+1)

=20,11x100

=2011

Answer 3

20,11 x 36 + 63 x 20,11 + 20,11

= 20,11 x 36 + 63 x 20,11 + 20,11 x 1

= 20,11 x ( 36 + 63 + 1 )

= 20,11 x 100

= 2011

Answer 4

\(20,11\times36+63\times20,11+20,11\)

\(=20,11\times\left(36+63+1\right)\)

\(=20,11\times100\)

\(=2011\)

_Chúc bạn học tốt_

Answer 5

\(20,11\times36+63\times20,11+20,11\)

\(=20,11\times36+63\times20,11+20,11\times1\)

\(=20,11\cdot\left(36+63+1\right)\)

\(=20,11\times100\)

\(=2011\)

Chúc bạn học tốt !!!

Answer 6
