Question

only answer needed .......no process required
$\frac{7 \sqrt{3} }{ \sqrt{10} + \sqrt{3} } - \frac{2 \sqrt{6} }{ \sqrt{6} + \sqrt{5} } - \frac{3 \sqrt{2} }{ \sqrt{15} - 3 \sqrt{2} }$
is the answer -15???????

Answer 1

it's 13.20 . ...... .... ..

Answer 2

After solutions, we get √3 - 2√6 + √2.

Doing with approximate values of them, we get,

1.732 - (2 x 2.449) + 1.414 = - 1.752

So the answer is not - 15.
