Answer
$.000000403$
Work Step by Step
We are given the number $4.03\times10^{-7}$. Since the exponent is negative, move the decimal 7 places to the left.
Note that 7 places to the left will be 6 decimal places past the first digit (4), so we will add 6 zeroes before 4.
$4.03\times10^{-7}=.000000403$
