Answer:

11021

Step-by-step explanation:

Using the identity

(x+ a) (x+b )= 2x + (a+b)x + ab,

we get,

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

⇒200 + 1000 + 21

⇒ 11021

Hope this helps. Mark me as the brainliest if it does!!

$103 \times 107 \\(100 + 3) \times (100 + 7) \\ {100}^{2} + (3 + 7)100 + 3 \times 7 \\ 10000 + 1000 + 21\\ 11021$

I hope it helps you :) :)
