0.000000591 written in scientific notation is $5.91$ x ${10}^{-} 7$.

#### Explanation:

The coefficient is written ranging from $1.0$ to $9.99$.

Look at $0.000000591$. The space after the first non-zero number counting from left to right is where your decimal point will go. To make the coefficient between $1.0$ and $9.99$, move the decimal place $7$ times to the right:

$0.000000591$ $\Rightarrow$ $5.91$

All the zeros before the $5$ in $5.91$ do not have to be written since $0$ has no value.

Finally, after moving the decimal point $7$ times to the right, indicate the change you have made to $0.000000592$ by adding "x ${10}^{-} 7$" after $5.91$.

$\therefore , 0.000000591$ written in scientific notation is $5.91$ x ${10}^{-} 7$.
