Use (a+b) 2 = a 2 + 2ab + b 2 to evaluate the following: (101) 2

(101) 2 = (100 + 1) 2 Using (a + b) 2 = a 2 + 2ab + b 2 , (100 + 1) 2 = (100) 2 + 2(100)(1) + (1) 2 = 10000 + 200 + 1 = 10201

(101)² = (100 + 1)²

Using (a + b)² = a² + 2ab + b²,

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

= 10000 + 200 + 1 = 10201
