Answer 2

$3 \sqrt{5} - 7 \sqrt{3} - (5 \sqrt{3} + 7 \sqrt{5} ) = -29.728$

Solution:

Given that,

We have to find to subtract 5 root 3 +7 root 5 from 3 root 5 -7 root 3

Which means,

$3 \sqrt{5} - 7 \sqrt{3} - (5 \sqrt{3} + 7 \sqrt{5} )$

Remove the parenthesis and solve

$3 \sqrt{5} - 7 \sqrt{3} - 5 \sqrt{3} - 7 \sqrt{5} \\\\Combine\ like\ terms\\\\3 \sqrt{5} - 7 \sqrt{5} - 7 \sqrt{3} - 5 \sqrt{3}\\\\-4\sqrt{5} - 12\sqrt{3}$

$Simplify\\\\-4 \times 2.236 -12 \times 1.732 \\\\\-8.944-20.784\\\\-29.728$

Thus, the solution is -29.728
