To express \(1.4 \times 10^{-6}\) in standard decimal notation, you move the decimal point 6 places to the left because of the negative exponent.
Starting with 1.4:
- Move the decimal 1 place left: 0.4
- Move the decimal 2 places left: 0.04
- Move the decimal 3 places left: 0.004
- Move the decimal 4 places left: 0.0004
- Move the decimal 5 places left: 0.00004
- Move the decimal 6 places left: 0.0000014
Thus, \(1.4 \times 10^{-6} = 0.0000014\).
