1. Problem Description
The problem asks us to convert numbers written in scientific notation to standard form. We need to do this for the following numbers:
19)
20)
21)
22)
23)
24)
2. Solution Steps
To convert a number from scientific notation to standard form, we multiply the number by the power of
1
0. If the exponent is positive, we move the decimal point to the right. If the exponent is negative, we move the decimal point to the left.
19) : Move the decimal point 6 places to the left. This gives us 0.
