Answer 2

Answer:

10094.

Step-by-step explanation:

Here we will use the identity of (x + a)(x + b) = x^2 + (a + b)x + ab.

How?

It is given that 103 × 98.

This can be written as (100 + 3)(100 - 2)

Now, here,

x = 100.

a = 3

b = -2.

Put the values to get,

(100)² + (3 +(-2))100 + 3 × (-2)

= 10000 + 100(1) +  (-6)

= 10100 - 6

= 10094.

Hope it helps.
