$$3.8 \times 10^{-6}=0.0000038$$

Work Step by Step

$$3.8 \times 10^{-6}$$ Recall that scientific notation is expressed in the form: $$a\times10^{n}$$ To convert from scientific notation to decimal notation, move the decimal point $n$ places to the right if $n$ is positive. If $n$ is negative, move the decimal point in a to the left $|n|$ places. Since $n=-6$ is negative, the decimal point should be moved $6$ places to the left. The resulting value is: $$0.0000038$$
