Ma poate ajuta cineva va rog frumos?

1. Calculati :
a)
[tex]4 \sqrt{12} - 3 \sqrt{27} + \sqrt{75 } [/tex]

b)
[tex]2 \sqrt{3} \times 4 \sqrt{2} [/tex]
c)
[tex]4 \sqrt{2} \times ( \sqrt{18} + 2 \sqrt{8} )[/tex]


2.
[tex]( \sqrt{2} + 1 ) \times ( \sqrt{2} - 1) [/tex]
b)
[tex]2 \sqrt{3} \times (4 \sqrt{2} - \sqrt{24} )[/tex]
c)
[tex]( \sqrt{2} - 3) \times (1 - \sqrt{2} )[/tex]
d)
1/√2 + 2/√8 + 3/√18

e) (2/5√3 - 1/√12 - 3/2√3) : 1/√75

f) 2/√3 +(√5/5√2)^-1 + 2*(2/√27-5√10)

Dau coroana
