The expression shown in the image is:

$\frac{5 \cdot 10^{-6} \cdot 10^6}{(10^2)^{-3}}$

Let's simplify this step by step:

1. Simplify the multiplication in the numerator:

   $10^{-6} \cdot 10^6 = 10^{-6 + 6} = 10^0 = 1$

   So, the expression becomes:

   $\frac{5 \cdot 1}{(10^2)^{-3}}$

2. Simplify the denominator:

   $(10^2)^{-3} = 10^{2 \cdot (-3)} = 10^{-6}$

   Now, the expression is:

   $\frac{5}{10^{-6}}$

3. When dividing by $10^{-6}$, you can multiply by its reciprocal:

   $\frac{5}{10^{-6}} = 5 \cdot 10^6$

So, the simplified result is:

$5 \cdot 10^6$
