Question

103×107evaluate the following products without multiplying directly​

Answer 1

Answer:

11021

Step-by-step explanation:

103 * 107

=(100+3)(100+7)

Using Identity (x + a)(x + b) = x ^ 2 + (a + b) * x + ab where x = 100 , a = 3 b = 7

=(100)^ 2 +(3+7)100+(3)(7)

=1000000+(10)(100)+21

=1000000+1000+21

=11021

Answer 2

Step-by-step explanation:

*103x107*

(100+3)(100+7)

Use the property (a+c)(a+b) Where a is 100 And c is 7 .

100(100×7)+3(100+7)

100^2 + 100×7 + 100×3+ 3×7

10000+700+300+21

=11021
