Answer 1

Step-by-step explanation:

Find the value of the following: (a) 297 x 17 + 297 x3 (b) 54279 x 92 + 8 x54279 (c) 81265 x 169 - 81265 x69 (d) 3845 x 5 x 782 + 769 x 25 x218

(a) 297 x 17 + 297 x3

= 297 x (17 +3)

= 297 x 20

= 5940

(b) 54279 x 92 + 8 x 54279

= 54279 x (92 +8)

= 54279 x 100

=5427900

(c) 81265 x 169 – 81265 x 69

= 81265 x (169 – 69)

= 81265 x 100

= 8126500

(d) 3845 x 5 x 782 + 769 x 25 x 218

= 3845 x 5 x 782 + 769 x 5 x 5 x 218)

= 3845 x 5 x 782 + 3845 x 5 x 218

= 3845 x 5 x (782 +218)

= 3845 x 5 x 1000

=19225000
