What's up with 1.769e2? (scientific notation for doubles)

+15 votes

In Question 3 on last year's Midterm 1 exam, we find 1.769e2

What does this mean and how do I evaluate it?

This is "scientific notation", and it means 1.7692 x 10^2 (i.e., 1.7692 times 10 raised to the 2nd power) 

     = 176.92

Similarly 3.8e3 = 3.8 x 10^3 = 3800.0
