Answer 1

Hey friend,
Here is the answer you were looking for:
${(101)}^{2} \\ \\ we \: can \: write \: it \: as \: \\ {(100 + 1)}^{2} \\ \\ using \: the \: identity \\ (a + b)^{2} = {(a)}^{2} + {(b)}^{2} + 2ab \\ \\ {(100 + 1)}^{2} = {(100)}^{2} + {(1)}^{2} + 2 \times 100 \times 1 \\ \\ = 10000 + 1 + 200 \\ \\ = 10201$

Hope this helps!!!
