Question

Pls add this with steps.....

Answer 1

$3 \sqrt{3} - 5 \sqrt{2}$
3×1.732-5×1.414
5.196-7.071
=-1.874
$\sqrt{3} + 3 \sqrt{2}$

1.732+3×1.414
1.732+4.242
=5.974
$7 \sqrt{2} + 4 \sqrt{3} - 3 \sqrt{5}$
7×1.414+4×1.732-3×2.236
7×1.414+4×1.732-6.708
9.899+6.928-6708
=23.535
$2 \sqrt{3} - \sqrt{2} + \sqrt{5}$
2×1.732-1.414+2.236
3.464-3.650
=-0.186
