\(45.\left(23-17\right)+23.\left(45-17\right)\)
\(=45.6+23.28\)
\(=270+644\)
\(=914\)
45 x ( 23 - 17 ) + 23 x ( 45 - 17 )
= 45 x 23 - 45 x 17 + 23 x 45 - 23x 17
= ( 45 x 23 - 45 x 23 ) - ( 45 x 17 + 23 x 17 )
= 0 - 17 x ( 45 + 23 )
= -17 x 1035
= -17595
45x(23−17)+23x(45−17)
=45.6+23.28
=270+644
= 914
