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

To convert a number to scientific notation, you first need to divide that number by a power of 10 such that the answer has units as the greatest place value. In this case, you can divide by 100,000 to give 4.2 The next step is to display the power of 10 you used alongside this number as a multiplication. We used 100,000 which is the 5th power of 10 or 105. Thus, 420,000 in scientific notation is: 4.2x105
This number in scientific notation is 9.8x10-5.
It is: 2.7*10^0 in scientific notation
The scientific notation for 89,450 is: 8.945 × 104
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.
