Question

5V2 -2V2 + V5 - 2V20 + V500

Answer 1

5√2  -  2√2  +  √5  -  2√20  +  √500
5√2  - 2√2 + √5 - 2 √ 2² . 5  + √2² . 5² . 5
5√2 - 2√2 + √5  - 2.2√5 + 2.5√5
5√2  - 2 √2  +  √5 - 4√5 + 10√ 5
√2(5 - 2)  +  √5(1 - 4 + 10 )
3√2  +  7√5

Answer 2

$5\sqrt{2} - 2\sqrt{2} + \sqrt{5} - 2\sqrt{20} + \sqrt{500} 5\sqrt{2} - 2\sqrt{2} + \sqrt{5} - 2\sqrt{5.2^2} + \sqrt{10^2.5}$

$5\sqrt{2} - 2\sqrt{2} + \sqrt{5} - 2.2\sqrt{5} + 10\sqrt{5} 5-2 (\sqrt{2}) + 1-4+10 (\sqrt{5})$

$3 \sqrt{2} + 7\sqrt{5}$
