key idea

A number written in scientific notation has two factors multiplied together. The first factor must be at least 1 and less than 10, and the second factor must be a power of 10.

To compare two numbers written in scientific notation, first compare the powers of 10. If the powers of 10 are equal, then compare the coefficients.

solution

Both numbers are written in scientific notation. To compare them, look at the powers of 10.
