Question

find the value of 103×197 using the formula​

Answer 1

Answer:

Step-by-step explanation:

To solve this we should first convert it into

(100+3) x (100 + 97)

Then we should use the formula (x+a) (x+b)= X^2 +(a+b)x + ab

Then it will become 100^2 + 100(100) + 97 x 3

= 10000 + 10000 + 291

= 20291
