Answer:
The options are not really clear, however, the answer is 3.2 × 10^3ug
Explanation:
Milligram (mg) and microgram (ug) are interconvertible measurements of mass or weight. One microgram (ug) is a millionth gram while one milligram (mg) is a thousandth gram.
Hence, one milligram is a thousandth microgram i.e. 1 mg = 1000 ug
Therefore, a measurement of 3.2mg in ug will be; 3.2 × 1000
= 3200
= 3.2 × 10^3 ug
Hence, an equivalent measurement of 3.2mg is 3.2 × 10^3ug.
