a) 3 506 x 25 x 4

b) 467 x 46 + 467 x 54

Answer 1

a) 3 506 x 25 x 4 

= 3 506 x (25 x 4)

= 3 506 x 100

b) 467 x 46 + 467 x 54

= 467 x (46 + 54)

=467 x 100

 = 46700

Answer 2

a) 3 506 x 25 x 4

=   3506.100

=350600

b) 467 x 46 + 467 x 54

= 467.(46+54)

=467.100

=46700

Answer 3

a) 3 506 x 25 x 4

= 3506 x (25 x 4)

= 3506 x 100

= 350 600

b) 467 x 46 + 467 x 54

= 467 x (46 + 54)

= 467 x 100

= 46 700

Answer 4

a) \(3506\times25\times4\)

\(=3506\times100\)

\(=350600\)

b) \(467\times46+467\times54\)

\(=467\times\left(46+54\right)\)

\(=467\times100\)

\(=46700\)
