Answer 1

1.

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

2. supraunitar= A/B, unde A> B

Deci raspunsul este b)

3. d) 12°

4. c)

5.

$\frac{( - 7 \sqrt{2}) - 2 \sqrt{2} + 8 \sqrt{2} + 13 \sqrt{2} }{4} = \frac{ - 9 \sqrt{2} + 21 \sqrt{2} }{4} = \frac{12 \sqrt{2} }{4} = 3 \sqrt{2}$

Deci Cristina a rezolvat corect.
