Question

The product of 99 and predecessor of 100 is

Answer 1

Hello Dear!!!

Here's your answer....

predecessor of 100 is 99

product of 99 and 99 is

(99)^2

99 can be written as (100 - 1)

(100 - 1)^2

it is in the form of (a-b)^2

(a-b)^2 = (a)^2 - 2ab + (b)^2

(100-1)^2

here,

a is 100

b is 1

(100)^2 - 2*100*1 + (1)^2

10000 - 200 + 1

9800 + 1

9801

9801 is the answer....
