Step 1

Consider the expressions as,

$\frac{7}{\sqrt{z}}$

To simplify the expression, rationalise the denomination and simplify the radical in the denomination

So,

$\frac{7}{\sqrt{z}} = \frac{7 \times \sqrt{z}}{\sqrt{z} \cdot \sqrt{z}}$

$= \frac{7 \sqrt{z}}{\sqrt{z^{2}}}$

$= \frac{7 \sqrt{z}}{z}$

Hence, the simplification of the given expression is $\frac{7 \sqrt{z}}{z}$
