Ok, you know what scientific notation is?

oswaldmurphy · Answer

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.

oswaldmurphy · Answer

So your answer would be,  4.372 × 10^9. Describe it exactly how you found the answer.
