Question

A spaceship traveled 32 million miles. In scientific notation that is _____ miles.

Answer 1

It would be 3.2 * 10^7

Answer 2

The answer is 3.2 X $10^{7}$

32 million written out is 32,000,000 which in scientific notation is 3.2 X $10^{7}$

Because $10^{7}$= 10,000,000 

So, 3.2*10,000,000=32,000,000
