Question

Using. Identity 103*107​

Answer 1

$\sf\implies 103 \times 107 \\ \\\sf \implies (100 + 3)(100 + 7) \\ \\\sf \implies {(100)}^{2} + (3 + 7)100 + 3 \times 7 \\ \\ \sf\implies10000 + 1000 + 21 \\ \\ \large\boxed{ \sf \green{ \implies 11021}}$

Identity Used :

$\boxed{ \sf \red{ (x + a)(x + b) = {x}^{2} + (a + b)x + ab}}$

✰✰ ANSWER ✰✰

$⇢\textbf{100+3}$

$⇢\textbf{100+7}$

➜Using Identity : -

$⇢[x+a][x+b]={x}^{2}+(a+b)x+ab$

➜Now : -

$⇢({100)}^{2}+(3+7)×(100)+(3×7)$

$⇢10000+1000+21$
