Which numbers are greater than 5*10-6? Choose all answers that are correct.

a. 9*10-8

b. 7*10-6

c. 5*10-4

d. 4*10-6

e. 8*10-9

I got b and c. Also, you have to remember, just because the exponent is a bigger number does not mean it's right. Negative numbers go left, so the smaller number would be bigger.
