Arrange the numbers in scientific notation from greatest to least according to their values. tiles 3.1 × 10-22.01 × 10-34.2 × 10-51.03 × 10-12.32 × 10-4

For this case we have the following numbers:
 3.1 × 10-2
 2.01 × 10-3
 4.2 × 10-5
 1.03 × 10-1
 2.32 × 10-4
 To order the numbers, we must look at the exponent. The greater the exponent, the greater the number.
 We have then that the order of greatest to least is:
 1.03 × 10-1
 3.1 × 10-2
 2.01 × 10-3
 2.32 × 10-4
 4.2 × 10-5
