Which of the following is a complex number?

daser333 [38]

Answer:

C. $3 \sqrt{ \frac{7}{5} } + \sqrt{ - \frac{9}{5} }$

Step-by-step explanation:

Recall that:

$\sqrt{ - 1} = i$

For this particular question, you just have to look for the radical containing a negative sign under the square root i.e a negative radicand.

That will be option C.

This is given as

$3 \sqrt{ \frac{7}{5} } + \sqrt{ - \frac{9}{5} }$

This can be rewritten to reveal the complex part as:

$3 \sqrt{ \frac{7}{5} } + \sqrt{ \frac{9}{5} }i$

Therefore the correct answer us option C
