a x 10b
Follow the steps below to see how 30,000 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 30,000
New Number: 3.0000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 3 . 0 0 0 0
Decimal Count: 1 2 3 4
There are 4 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3 (Please notice any zeroes on the end have been removed)
b = 4
Now the whole thing:
