1.9 x 10=19
4.2x10=42
Now just find out how to multiply 19 -8 times and how to multiply 42, -13 times.
4.2x10=42

Not 42 x -13 and 19 x -8, that's the complete opposite.

You have to divide:
1.9x10^-8 รท (4.2x10^-13)
= appr .45 x 10^5
= .45 x 100000
= appr 45,000 times as large
1.9x10^-8 รท (4.2x10^-13)
= appr .45 x 10^5
= .45 x 100000
= appr 45,000 times as large
