Question

5. Calculaţi: a) |x-2√3|= √3​

Answer 1

Explicație pas cu pas:

$|x - 2 \sqrt{3} | = \sqrt{3}$

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

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

$x \in \Big\{ \sqrt{3}; 3\sqrt{3}\Big\}$

Answer 2

x-2V3 = V3

x = V3+2V3

x = 3V3

sau

x-2V3 = -V3

x = -V3+2V3

x = V3

x = {V3, 3V3}
