When you write things in standard notation, you move the decimal point to the left or to the right, depending on the number and whether it is negative or positive. To convert [tex]6.92 * 10^{-8}[/tex] to standard notation, we need to move the decimal point left (because the exponent is negative) 8 places:
[tex]6.92 * 10^{-8} = .0000000692[/tex]
[tex]6.92 * 10^{-8}[/tex] in standard notation is .0000000692.
