Answer:

Final Answer.

Step-by-step explanation:

Given,

101 x 103

We can also write it as,

101 x 103 = (100 + 1) (100 + 3)

Using the identity, (x + a) (x + b) = $x^{2}$ + (a + b)x + ab

We have,

(100 + 1) (100 + 3) = $(100)^{2}$ + (1 + 3)100 + (1)(3)

= 10000 + 4(100) + 3

= 10000 + 400 + 3

= 10403

Hence, the final answer is 10403.
