\(=306\cdot100=30600\)

Answer 2

306*41+58*306+306

=306*(41+58+1)

=306*100=30600

Answer 3

= 306 . (41 + 58 + 1)

Answer 4

 306x41+58x306+306=306x41+58x306+306x1

                                   =306x(41+58+1)

                                   =306x100=30600

Answer 5

306.41+58.306+306=306.(41+58+1)=306.100=30600

Answer 6

306 x 41 + 58 x 306 + 306

= 306 x 41 + 306 x 58 + 306 x 1

= 306 x (41 + 58 + 1)

= 306 x 100

= 30600

Answer 7

306 x 41 + 58 x 306 + 306

= 306 x 41 + 58 x 306 + 306 x 1

= 306 x ( 41 + 58 + 1 )

= 306 x 100

= 30600
