Answer:
1. 3 x 10^−6:
- The decimal number is 3.
- The power of 10 is −6. This means we move the decimal point 6 places to the left.
- Therefore, 3 x 10^−6 can be written as 0.000003.
2. 2.4 x 10^−5:
- The decimal number is 2.4.
- The power of 10 is −5. This means we move the decimal point 5 places to the left.
- Therefore, 2.4 x 10^−5 can be written as 0.000024.
To summarize, 3 x 10^−6 is equivalent to 0.000003 and 2.4 x 10^−5 is equivalent to 0.000024. These numbers are both very small and can be represented more conveniently in scientific notation.
