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
A large number that would normally be expressed in scientific notation.
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: 4.2 x 10^2
It is: 4.2*10^2 when in scientific notation
4.2 x 108
times by the little number like .420 is 80
A large number that would normally be expressed in scientific notation.
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: 2.7*10^0 in scientific notation
This number in scientific notation is 9.8x10-5.
The scientific notation for 89,450 is: 8.945 × 104
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
