Question

13.(23+22)-3.(17+28)

Answer 1

13 . ( 23 + 22 ) - 3 . ( 17 + 28 ) 

= 13 . 45 - 3 . 45

= 45 . ( 13 - 3 )

= 45 . 10

= 450 

Answer 2

\(13.\left(23+22\right)-3.\left(17+28\right)\)

\(=13.45-3.45\)

\(=45.\left(13-3\right)\)

\(=45.10\)

\(=450\)

Answer 3

13 . ( 23 + 22 ) - 3 . ( 17 + 28 )

= 13 . 45 - 3 . 45

= 45. ( 13 - 3 )

= 45 . 10

= 450

Answer 4

13. (23+22)-3.(17+28)=13.45-3.45=45.(13-3)=45.10=450
