$\huge(101) ^{2}$
​

Answer 1

Answer:

★Solution

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

$= (100) ^{2} + 2 \times 100 \times 1 + (1) ^{2}$

$= 10000 + 200 + 1$

$\green{=} \red{10201}$

$\large{★}\small{{\fbox{\textsf{\textbf{Using formula:-}}}}}$

$\blue{ \longrightarrow}(a + b)^{2} = {a}^{2} + 2ab + {b}^{2}$
