Hello, I'm studying for the GMAT and can use all the help i can get. Thank God for you all and the math help forum.

Here's my question:

The Product of 26,11,3 is closet to which of the following powers of 10?

a) 10^4
b) 10^3
c) 10^5
d) 10^2

I know the answer is b) 10^3, but i had to multiply the entire problem out.

I wanted to know, is there a short handed way to answer this problem. If so, it'll save me valuable seconds on the GMAT. Any help would be greatly appreciated.

Thanks,
