$5.4 \cdot {10}^{7}$

Explanation:

We have $54 000 000$
It can be translated as $5.4 \cdot 10000000$
Which is $5.4 \cdot 10000 \cdot 1000$
A power of $10$ is $10$ at the power of how many $0$s we have, if that makes sense.

So $1000$ is ${10}^{3}$ since we have 3 $0$s.
$10000$ is ${10}^{4}$ because there are 4 $0$s.
So we have $5.4 \cdot {10}^{4} \cdot {10}^{3} = 5.4 \cdot {10}^{4 + 3} = 5.4 \cdot {10}^{7}$
