Answer 2

Answer:

1.3

Step-by-step explanation:

Given that

$\frac{2.3 \times 2.3 - 0.3 \times 0.3}{2.3 \times 2.3 - 2 \times 2.3 \times 0.3 + 0.3 \times 0.3}$

To simplify it

Solution

As we know that

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

and

${a - b}^{2} = {a}^{2} - 2ab + {b}^{2}$

Hence given expression will be

$\frac{ {2.3}^{2} - {0.3}^{2} }{(2.3 - 0.3 {)}^{2} }$

$\frac{(2.3 - 0.3)(2.3 + 0.3)}{(2.3 - 0.3 {)}^{2} }$

now by division

$\frac{2.3 + 0.3}{2.3 - 0.3}$

by solving addition and subtraction

$\frac{2.6}{2}$

by division we get

$1.3$

hence this is the answer.
