Question

using Identity find 1032

​

Answer 1

Given, 1.03$\small{2}$

=(1+0.03) $\small{2}$

We know, (a+b) $\small{2}$ =a$\small{2}$ +2ab+b $\small{2}$

Then,

1.03 $\small{2}$ = (1+0.03) $\small{2}$

=1 $\small{2}$+(0.03) $\small{2}$ +2×1×0.03

=1+0.0009+0.06

=1.0609.

Therefore, option B is correct.
