Question

va rog imi trebue foarte urgent tot asta​

Answer 1

Explicație pas cu pas:

a)

$= 2 - \sqrt{3} + \sqrt{3} - 1 = 1$

b)

$= 2 \sqrt{2} - \sqrt{3} + \sqrt{2} - 1 + \sqrt{3} - 1 = 3 \sqrt{2} - 2$

c)

$= \sqrt{5} - 2 + \sqrt{5} + \sqrt{3} + 2 - \sqrt{3} = 2 \sqrt{5}$

d)

$= \sqrt{2} + 3 + 3 - \sqrt{2} = 6$

e)

$= 2 \sqrt{3} - 3 \sqrt{2} + 2(2 - \sqrt{3}) + 3( \sqrt{2} - 1) = 2 \sqrt{3} - 3 \sqrt{2} + 4 - 2 \sqrt{3} + 3 \sqrt{2} - 3 = 1$
