Question

Rezultatul calculului (4-2√3)-√108:2√3

Answer 1

$(4 - 2 \sqrt{3} ) - \frac{ \sqrt{108} }{2 \sqrt{3} }$

$= (4 - 2 \sqrt{3} ) - \frac{6 \sqrt{3} }{2 \sqrt{3} }$

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

$= 4 - 2 \sqrt{3} - 3$

$= 1 - 2 \sqrt{3}$

Answer 2

$(4 - 2 \sqrt{3} ) - \sqrt{108} \div 2 \sqrt{3} \\ = (4 - 2 \sqrt{3} ) - 2 \sqrt{36} \\ = 4 - 2 \sqrt{3} - 2 \times 6 \\ = 4 - 2 \sqrt{3} - 12 \\ = - 8 - 2 \sqrt{3}$
