If a = \(\frac{\sqrt {3}}{2}\), find (\(\sqrt {1+a}+\sqrt {1-a}\))
Answer & explanation
Correct answer: option 2
If the equation is in the form of (\(\sqrt {1+a}+\sqrt {1-a}\))
then it can be written as
\(\frac{\sqrt {3}}{2}\) + \(\frac{1}{2}\) + \(\frac{\sqrt {3}}{2}\) -\(\frac{1}{2}\)
\(\frac{\sqrt {3}}{2}\) + \(\frac{\sqrt {3}}{2}\) = \(\sqrt {3}\)
