$36000$.

#### Explanation:

Just expand the powers of ten, noting that ${10}^{k}$ is simply a one followed by $k$ zeroes.

So, ${10}^{4} = 10000$, and ${10}^{3} = 1000$.

This means that $3 \cdot {10}^{4} = 3 \cdot 10000 = 30000$, and
$6 \cdot {10}^{3} = 6 \cdot 1000 = 6000$.

Finally,

$30000 + 6000 = 36000$.
