what is is \(2.06 \times 10^{-9}\). is normal from

Answer 1

The number \(2.06 \times 10^{-9}\) is expressed in scientific notation. To convert it to normal form (or standard decimal notation), you need to move the decimal point 9 places to the left, since the exponent is negative.

So:

1. Start with \(2.06\).

2. Move the decimal point 9 places to the left:

   • Move 2 places left to get \(0.0206\).
   • Move another 7 places to the left (adding zeros as needed) will give you \(0.00000000206\).

Therefore, \(2.06 \times 10^{-9}\) in normal decimal notation is:

\[ 0.00000000206 \]
