p/1. Rezultatul calculului 3V3 pe 2-2V3pe 5

11. 3 B. c. 13 D.
10​

Answer 1

$\frac{ \frac{3 \sqrt{ 3} }{2 - 2 \sqrt{3} } }{5}$

$\frac{15 \sqrt{3} }{2 - 2 \sqrt{3} }$

$\frac{15 \sqrt{3} }{2 - 2 \sqrt{3} } \times \frac{2 + 2 \sqrt{3} }{2 + 2 \sqrt{3} }$

$\frac{15 \sqrt{3} \times (2 + 2 \sqrt{3} )}{(2 - 2 \sqrt{3}) \times (2 + 2 \sqrt{3)} }$

$\frac{15 \sqrt{3} \times 2(1 + \sqrt{3} )}{4 - 4 \times 3}$

$\frac{15 \sqrt{3} \times 2(1 + \sqrt{3} ) }{4 - 12}$

$\frac{15 \sqrt{3} \times 2(1 + \sqrt{3} )}{ - 8}$

$\frac{15 \sqrt{3} \times (1 + \sqrt{3} )}{ - 4}$

$\frac{15 \sqrt{3} + 45}{ - 4}$
