Given: The terms a. (-57) x (-19) + 57

                              b. 15 x (-25) x (-4) x (-10)

To find: The product using suitable properties.

Solution:

  • Now we have given two terms: a. (-57) x (-19) + 57

                                                             b. 15 x (-25) x (-4) x (-10)

  • Consider a. (-57) x (-19) + 57

               (57) x (19) + 57

  • Taking 57 common, we get:

               57 x ( 19 + 1 )

               57 x 20

               1140

  • Consider b. 15 x (-25) x (-4) x (-10)

               15 x { (-25) x (-4) } x (-10)

               15 x { (100) } x (-10)

               -15000

Answer:

            So the products are: 1140 and -15000
