There's nothing to change here. There is no advantage or reason to write 4.20 in scientific notation. Technically, however, it could be written as 4.20 × 100, but this is not normally done.
It is: 4.2 x 10^2
4.2 x 108
1,420 is expressed as 1420.0. Move 3 decimal places to the left, so the exponent for base 10 is 3. Therefore, in scientific notation, the given value is: 1.42 x 103
It is 8.9*10^-5 in scientific notation
It is "(scientific notation)".
It is: 4.2 x 10^2
4.2 x 108
It is: 4.2*10^2 when in scientific notation
times by the little number like .420 is 80
1,420 is expressed as 1420.0. Move 3 decimal places to the left, so the exponent for base 10 is 3. Therefore, in scientific notation, the given value is: 1.42 x 103
It is 8.9*10^-5 in scientific notation
It is "(scientific notation)".
This number in scientific notation is 9.8x10-5.
The scientific notation for 89,450 is: 8.945 × 104
It is: 2.7*10^0 in scientific notation
9.32 x 105 already is in scientific notation.9.32 x 105 already is in scientific notation.9.32 x 105 already is in scientific notation.9.32 x 105 already is in scientific notation.
There is no true opposite of scientific notation, but the closest answer is Standard Notation.
