Question

Simplify the following using suitable properties:

1. (-1905) x (-2) + (-1905) x (-98)
2. (1579 x 865) - (579 x 865)​

Answer 1

Answer:

It will be solved by distributive property

Step-by-step explanation:

$1. \: ( - 1905) \times ( - 2) + ( - 1905) \times ( - 98) \\ = ( - 1905) \times ( (- 98 ) + ( - 2)) \\ ( - 1905) \times ( - 100) = 190500$

$2. \: (1579 \times 865) - (579 \times 865) \\ 865 \times (1579 - 579) \\ 865 \times 1000 = 865000$
