The power of 10 is -5
Move the decimal point to the right until the first significant number and in this problem it is 2. It took 5 places to the right until going past the 2 and the number would be negative because going right past the decimal point will make any power negative.
The answer is A. 5 is not an even number, so both events can't take place together.
I think the sabers are X=2 and X=-2
Not 100% sure this is right but
