9 times 8 witch is 72 72 divided by 8 equals 9 and 72 divide by 9 equals 8
If that helps, but I'm pretty sure the answer is -1 that is what I have found in Google that is what all the answers are that in finding.
My calculator says bad expression.
D is not in correct scientific notation. To be correct, the answer would be 5.0 x 10^2
