A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

How do you convert to scientific notation?
To convert a number to scientific notation, place or move the decimal point of a number until the coefficient of the number is greater than 1 and less than 10. Record down the coefficient (a) and count the number of steps the decimal point was moved. The number of steps moved (n) is taken as the exponent.
How do you write 0.00001 in scientific notation?
We know that when we move the decimal to the right then $ b $ is negative. Thus, $ b = – 5 $ . Hence, the scientific notation of [0.00001] is $ 1 times {10^{ – 5}} $ .
What is the scientific notation for 38000?
38,000 (thirty-eight thousand) is an even five-digits composite number following 37999 and preceding 38001. In scientific notation, it is written as 3.8 × 104.
How do you write 420000 in scientific notation?
420,000 (four hundred twenty thousand) is an even six-digits composite number following 419999 and preceding 420001. In scientific notation, it is written as 4.2 × 105.
How do you write 0.00000356 in scientific notation?
= 3.56*10⁻⁶.
How do you write 0.00018 in scientific notation?
0.0018 = 1.8 1000 = 1.8 × 1 1000 = 1.8 × 10−3. This alternative form is called scientific notation and is based on the fact that moving the decimal point to the left or right in a number is equivalent to multiplying the number by a power of 10 (negative powers amount to dividing).
How do you write 0.00000001 in scientific notation?
So we need to include (without applying it) a correction so that the actual overall value becomes the same.
- So we have 1.0109=0.000000001.
- But another way of writing 1109 is 10−9 so we end up with the form:
- 1.0×1109=1.0×10−9.
How do you write 3.8 in scientific notation?
This time, you move the decimal point to the right, 4 spaces. N = 3.8 and x = -4. So your number in scientific notation becomes: 3.8×10–4, or 3.

How do you write 0.000189 in scientific notation?
Take the decimal point and move it to the right until you pass the first non-zero digit (in this case number 1 ) stop there and get rid of the zeros. Count the movements of the point and use this value as NEGATIVE power of 10 that you’ll use as a multiplicator. You get: 1.89 and 4 movements of the point.

How do you write 0.25 in scientific notation?
Your number in decimal form is 0.25 . To get to “standard” scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, 0.25 becomes 02.5 . The leading zero is not significant, so 02.5 becomes 2.5 .
