Question

–
4. How do you write 9.4E
–
4 in standard form?

Answer 1

The notation \( 9.4E - 4 \) represents the number in scientific notation, where \( E \) stands for "exponent." This means \( 9.4 \times 10^{-4} \).

To convert this into standard form, you multiply \( 9.4 \) by \( 10^{-4} \):

\[ 9.4 \times 10^{-4} = 9.4 \times 0.0001 = 0.000094 \]

So, \( 9.4E - 4 \) in standard form is \( 0.000094 \).
