Question

Evaluate the value of (101)² by using suitable identity

Answer 1

(100+1)^2

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

(100+1)^2 = 100^2 + 1^2 + 2(100)1

                = 10000 + 1 + 200

                 = 10201

Answer 2

Answer:

(100+1)^2

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

(100+1)^2 = 100^2 + 1^2 + 2(100)1

                = 10000 + 1 + 200

                 = 10201
