The statement that best describes the value \( 6.7 \times 10^{-4} \) is:
6.7 x 10−4 is much smaller than 6.7.
This is because \( 6.7 \times 10^{-4} \) evaluates to \( 0.00067 \), which is indeed much smaller than \( 6.7 \). The other options are incorrect as well: \( 6.7 \times 10^{-4} \) is not larger than 6.7, and it is not equivalent to \(-6.7000\).
