Answer 1

Heya !!

Here is your answer !!

Answer 2

$Given : (8 + 3 \sqrt{7} )^2 + (8 - 3 \sqrt{7} )^2$

We know that (a + b)^2 = a^2 + b^2 + 2ab

We know that (a - b)^2 = a^2 + b^2 - 2ab.

Now,

$= \ \textgreater \ 8^2 + (3 \sqrt{7} )^2 + 2 * 8 * 3 \sqrt{7} + 8^2 + (3 \sqrt{7})^2 - 2 * 8 * 3 \sqrt{7}$

$= \ \textgreater \ 64 + 63 + 48 \sqrt{7} + 64 + 63 - 48 \sqrt{7}$

= > 127 + 127

= > 254.



Therefore the result is 254



Hope this helps!
