    1. (a) 297 x 17 + 297 x 3
      = 297 x (17 + 3)
      = 297 x 20
      = 5940

      (b) 54279 x 92 + 8 x 542379
      = 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
