36.28+36.82+64.69+64.41

Answer 1

=36*(28+82)+64(69+41)

=100*110=11000

Answer 2

\(=36.\left(28+82\right)+64.\left(69+41\right)=36.100+64.100\)

\(=\left(36+64\right).100=110.100=11000\)

Answer 3

36 . 28 + 36 . 82+ 64. 69 + 64 . 41

= 36 . ( 28 + 82 ) + 64 . ( 69 + 41 )

=36 . ( 100 + 10 ) + 64 . ( 100 +10 )

= 3600 + 360 + 6400 + 640

= ( 3600 + 6400 ) + ( 360 + 640 )

= 10000 + 1000

= 11000

Answer 4

36 . 28 + 36 . 82+ 64. 69 + 64 . 41

= 36 . ( 28 + 82 ) + 64 . ( 69 + 41 )

=36 . ( 100 + 10 ) + 64 . ( 100 +10 )

= 3600 + 360 + 6400 + 640

= ( 3600 + 6400 ) + ( 360 + 640 )

= 10000 + 1000

= 11000
