Homework Statement
How many inches are in an angstrom, given that 1 angstrom = 10^-8 cm.
Homework Equations
1 angstrom = 10^-8 cm
1 inch = 2.54 cm
The Attempt at a Solution
Ok, I convert 1 angstrom to 10^-8 cm, then divide by 2.54. This gives me 3.94 x 10^-8, but the book says it's actually 3.94 x 10^-9. What did I do wrong with the exponents? Is 10^-8 the same as 10 x 10^-8?
