Answer 1

Answer:

a= 0

b= $-\frac{\sqrt{42} }{12}$

Step-by-step explanation:

We can rewrite the expression to be:

$\frac{i\sqrt{7} }{i^{2}\sqrt{24} }$

We then can cancel out the i and we get

$\frac{\sqrt{7} }{\sqrt{24} i}$

Can be rewritten as

$\frac{\sqrt{7} }{2\sqrt{6} i}$

We then rationalize and get

$-\frac{\sqrt{42} }{12} i$
