Will someone please help me slove this problem.
A family refers to a group of two or more people related by birth, marriage,or adoption who resides together. In 2,00in Country A, the average family net worth was $460,000, and there were about 9.3 x 10 to the seventh power families. Calculate the total family net worthin Country A in 2000.
(Use scientific notation. Use the mutilpilcation symbol in the math palette as needed. Round to the nearest tenth as needed.)

460000 * 9.3 * 10^7 = 4.278 * 10^13

I don't undestand the final answer.

You got some serious studying to do then
460000 = 4.6 * 10^5
multiply that by 9.3 * 10^7
and you get 42.78 * 10^12
But that's not scientific notation. We need to make it
4.278 * 10^13
You can do the rounding needed. 
Okay I think I have the correct answer. Is it 42,780,000,000,000

That may be the answer, but they specifically asked you to use scientific notation.
