Question

choose the correct scientific notation for the given number. gaston was observing the influenza virus in the laboratory and found that the average measurement of each
8.725×10^(-8)
8.725×10^6
8.725×10^5
8.725×10^(-7)

Explanation:

Step1: Recall scientific - notation rule

Scientific notation is of the form $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer. Viruses are very small in size, so the exponent of 10 should be negative.

Step2: Analyze options

Among the given options, since viruses are microscopic and have very small dimensions, we need a negative - exponent. The most reasonable value for the size of an influenza virus in scientific notation is a very small number.

Answer:

$8.725\times 10^{-7}$ (assuming the size of the influenza virus is in a range that makes this the correct scientific - notation representation based on typical virus size magnitudes)
