Question

Find the value of the following:

(а)297x17+297x3

(б)54279x92+8x54279

(c)81265x169–81265x69

(d)3845x5x782+769x25x218​

Answer 1

Answer:

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
