Question

1. $5.5 \times 10^{-2} =$
2. $7 \times 10^{-5} =$
3. $2.3 \times 10^{-6} =$
4. $6.29 \times 10^{-3} =$
5. $1.07 \times 10^{-4} =$

Explanation:

Step1: Recall scientific notation to decimal conversion

For a number in the form \(a\times10^{-n}\), we move the decimal point in \(a\) to the left by \(n\) places.

Step2: Solve \(5.5\times10^{-2}\)

Move the decimal in \(5.5\) left 2 places: \(0.055\)

Step3: Solve \(7\times10^{-5}\)

Move the decimal in \(7\) (which is \(7.0\)) left 5 places: \(0.00007\)

Step4: Solve \(2.3\times10^{-6}\)

Move the decimal in \(2.3\) left 6 places: \(0.0000023\)

Step5: Solve \(6.29\times10^{-3}\)

Move the decimal in \(6.29\) left 3 places: \(0.00629\)

Step6: Solve \(1.07\times10^{-4}\)

Move the decimal in \(1.07\) left 4 places: \(0.000107\)

Answer:

1. \(0.055\)
2. \(0.00007\)
3. \(0.0000023\)
4. \(0.00629\)
5. \(0.000107\)
