Answer 1

To convert the number \(1.959 \times 10^{-4}\) into standard form, you move the decimal point four places to the left because of the negative exponent.

Starting with \(1.959\):

1. Move the decimal point one place left: \(0.1959\)
2. Move the decimal point two places left: \(0.01959\)
3. Move the decimal point three places left: \(0.001959\)
4. Move the decimal point four places left: \(0.0001959\)

So, \(1.959 \times 10^{-4} = 0.0001959\).

Thus, the correct answer is C. \(0.0001959\).
