$\frac{| cos x |}{\sqrt{sin x cos x}}$ $|cosx|/sqrt(sinxcosx)$

Explanation:

We can rewrite the entire expression as

$\frac{\sqrt{cos x}}{\sqrt{sin x}}$ $sqrt(cosx)/sqrt(sinx)$

We multiply both numerator and denominator by the numerator to rationalize.

$\frac{\sqrt{cos x}}{\sqrt{sin x}} \cdot \frac{\sqrt{cos x}}{\sqrt{cos x}}$ $sqrt(cosx)/sqrt(sinx) * sqrt(cosx)/sqrt(cosx)$

$\frac{cos x}{\sqrt{sin x cos x}}$ $cosx/sqrt(sinxcosx)$

Add an absolute value on the $cos x$ $cosx$ .

$\frac{| cos x |}{\sqrt{sin x cos x}}$ $|cosx|/sqrt(sinxcosx)$

Hopefully this helps!
