Answer 2

According to ur question,

${(203)}^{2}$

Can be written as,

${(200 + 3)}^{2}$

By using the property,

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

we get,

$( {200 + 3)}^{2} = {(200)}^{2} + 2 \times 200 \times 3 + {(3)}^{2}$

Now,

$40000 + 1200 + 9$

We get,

$41209$

Hence,

${(203)}^{2} = 41209$

u'r done!!
