Question

evaluate (101)2 by using (a+b)2 =a2+ 2ab +b2​

Answer 1

Answer:

10201

Step-by-step explanation:

${101}^{2} = {(100 + 1)}^{2}$

Where a = 100 and b = 1.

${100}^{2} + 2 \times 100 \times 1 + {1}^{2} \\ = 10000 + 200 + 1 \\ = 10201$

Answer 2

Answer:

10201

Step-by-step explanation:

(101)2=(100+1)2

=(100)2+(1)2+2(100×1)

=10000+1+200

=10000+201

(101)2=10201
