Question

using the identity find the answer
$(103 {}^{2} )$
​

Answer 1

Answer:

10609 is the answer getting from the identity

Step-by-step explanation:

$(103) {}^{2} = (100 + 3) {}^{2} \\ = 100 {}^{2} + 2 \times 100 \times 3 + 3 {}^{2} \\ = 10000 + 600 + 9 = 10609$

We many also find the direct multiply 103 by 103 and get the answer.. even we can less tedious method than the direct method to squaring.

Answer 2

$\huge\mathfrak{</p><p><strong>Answer:</strong></p><p>}$

(103)² = (100 + 3)²

Using identity

(a + b)² = a² + b² + 2ab}

(100 - 3)² = (100)² + (3)² + 2(100)(3)

» 10000 + 9 + 600

» 10600 + 9

» 10609.........[Answer]

$\huge\boxed{10609}$
