Question

Find the product using suitable properties
a. 950×99+950
b. 657×(-45)-657

Answer 1

$950 \times 99 + 950 \\ = 94050 + 950 \\ = 95000$

$657 \times ( - 45) - 657 \\ = - 29565 - 657 =30222$

Answer 2

Answer:

a.95000

b.-30222

Step-by-step explanation:

a. ab+ac=a(b+c)

=950(99+1)

=950(100)

=95000

b.ab-ac=a(b-c)

=657(-45-1)

=657(-46)

= -30222
