\(7,568\times99+7,568=7,568\times\left(99+1\right)=7,568\times100=756,8\)
\(34,89\times97+34,89:0,5+34,89\)
\(=34,89\times97+34,89\times2+34,89\)
\(=34,89\times\left(97+2+1\right)\)
\(=34,89\times100=3489\)
7,568×99+7,568
=7,568×99+7,568x1
=7,568×(99+1)
=7,568×100=756,8
34,89×97+34,89:0,5+34,89
=34,89×97+34,89x2+34,89x1
=34,89×(97+2+1)
=34,89×100
=3489
7,568 x 99 + 7,568 34,89 x 97 + 34,89 : 0,5 + 34,89
= 7,568 x 99 + 7,568 x 1 = 34,89 x 97 + 34,89 x 2 + 34,89 x 1
= 7,568 x ( 99 + 1 ) = 34,89 x ( 97 + 2 + 1 )
= 7,568 x 100 = 34,89 x 100
= 756,8 = 3489
