Question

Complete the equation, by supplying the missing exponent.

Answer 1

The answer is 1.927x102

Answer 2

$\bf \textit{so, the viruses have a total volume of }4.1\times 10^{16} \\\\\\ \textit{and we know that one virus alone is }4.7\times 10^{-14}\textit{ in volume} \\\\\\ 4.1\times 10^{16}\cdot 4.7\times 10^{-14}\implies (4.1\cdot 4.7)\times 10^{16-14}\implies 19.27\times 10^2 \\\\\\ 1.927\times 10^3\impliedby \textit{notice, we moved the dot over}$

keep in mind that, scientific notation uses only 1 integer to the left of the decimal point.
