$$5.607\times 10^{-6}$$

#### Work Step by Step

We know that scientific notation is: $a*10^b$, where $a$ must be between 1 and 10. Thus, we first multiply the two numerical values and the two values raised to a power. If the value of $a$ is between 1 and 10, we are done. If it is not, we must change the value of $b$ such that the value of $a$ is between 1 and 10. Doing this, we find: $$56.07\times 10^{5-12} \\ 56.07\times 10^{-7}\\ 5.607\times 10^{-6}$$
