The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

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}} $ .
How do you write 0.00042 in scientific notation?
Write the number 0.00042 in scientific notation. To write this number in scientific notation, you must first move the decimal 4 places from where it is in the original number to between the 4 and the 2. Since you are moving the decimal 4 places to the right, you will subtract from the exponent.
How do you write 0.00035 in scientific notation?
Now, we can say that [3.5 times {10^{ – 4}}] is the scientific notation of [0.00035].
How do you write 0.000938 in scientific notation?
The first step to converting a number into scientific notation is moving your decimal behind the first number between 1-10.
- In this case, your number is 0.000938 .
- (Another example would be 0.0000398 .
- Now that you’ve moved your decimal 4 places to the right behind 9, your new number is 9.38.
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 change to scientific notation on a TI 84?

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.

Will the exponent of the power of 10 be positive or negative when writing 0.00000008 in scientific notation?
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative.
