Answer 2

The required solution would be 25

Step-by-step explanation:

Given expression,

$\frac{18.43\times 18.43 - 6.57\times 6.57}{11.86}$

$=\frac{18.43^2 - 6.57^2}{11.86}$

Using the property a² - b² = (a+b)(a-b),

$\frac{(18.43+6.57)(18.43-6.57)}{11.86}$

$=\frac{25\times 11.86}{11.86}$

= 25
