Answer

$7.6\times10^{-4}$

Work Step by Step

To express $0.00076$ in scientific notation we must make the decimal come after the first nonzero digit. To do this we must move the decimal place over 4 to the right, dividing by $10^{-4}$. To keep the value the same, we must also multiply by $10^{-4}$, giving us $7.6\times10^{-4}$
