4.00*10^-8
The number that 10 is to the power of is the number of digits from the decimal place, except if the number is less than one (then you add one to the # of decimals and make it negative).
So,
100 = 10^2 because rightmost non-zero digit is 2digits from the decimal.
10 = 10^1 ... is 1 digit from the decimal.
1 = 10^0 ... is 0 digits from the decimal.
0.1 = 10^-1 because the first non-zero digit is 0digits from decimal place
(but we add one and make it negative because the number we
are converting to a power of 10 is less than one).
0.01 = 10^-2 ...digit is 1 digit away, +1 and make it
negative because it's less than one
0.001 = 10^-3 ... 2 digits away + 1 and make it neg
But wait, these are only multiples of 10! What if I have a number like 4 or 0.000000004?
Well, it's simple. You simply find out the power of 10 using the above rules and then multiply it by a factor (note that above rules do not take into account the value of the number, just its placement from the decimal place), then multiply it by a factor (usually the group of non-zero numbers, in this case 4).
So for the sake of example, lets use 0.04
using the above rules we can tell that the power of 10 we must use is 10^-3
However 10^-3 is 0.01, not 0.04. So we multiply 10^-3 by 4 so that it equals 0.04.
This gives us 4*10^-3
how do you write 4.252 10=
10 to the 9th power is: 1,000,000,000
10-4
10-7 = 0.0000001
100 can be written as 10 raised to the power of 2.

10 to the 9th power is: 1,000,000,000
0.000000001
10 to the fourth power = 104
10 to the fifth power = 105
a power of 10
10 000 000 = 10 to the power of 7
10-4
10 million is 10 to the 6th power. When you raise it to the power of 10 you are making it 10 to the 6x10th power i.e. 10 to the 60th power. to write it out you would write a 1 followed by 60 zeros before any decimal point.
0.01 = 10 × 10-3
10 to the power 1
10-7 = 0.0000001
