Answer»

ANSWER:

The product is 101\times 99=9999

Step-by-step EXPLANATION:

Given : Expression 101\times 99

To FIND : Evaluate the given product without actual MULTIPLICATION ?

Solution :

We can write product as,

101\times 99=(100+1)\times (100-1)

We know, (a+b)(a-b)=a^2-b^2

101\times 99=(100+1)(100-1) here a=100 , b=1

101\times 99=(100)^2-(1)^2

101\times 99=10000-1

101\times 99=9999

Therefore, The product is 101\times 99=9999
