Answer: Choice A) 8.742 * 10^7
=====================================
Work Shown:
[tex](a * 10^b) \times (c * 10^d) = a*c*10^{b+d}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 2.82*3.1*10^{4+3}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 8.742*10^{7}\\\\[/tex]
Extra info:
[tex]8.742 * 10^7 = 87,420,000[/tex]
which is a little over 87.4 million
