Question

Calcular: (Cos 60°. Sec30º – Tan30°)2 + (2Cos45° + Csec45°)2
​

Answer 1

Respuesta:

8

Explicación paso a paso:

${ (\frac{1}{2} \times \frac{2}{ \sqrt{3} } - \frac{1}{ \sqrt{3} } )}^{2} + { (\sqrt{2} + \sqrt{2}) }^{2} \\ { ( \frac{1}{ \sqrt{3} } - \frac{1}{ \sqrt{3} } ) }^{2} + {(2 \sqrt{2} )}^{2} \\ 4 \times 2 = 8$
