Answer:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 29,800,000
New Number: 2.9800000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 2 . 9 8 0 0 0 0 0
Decimal Count: 1 2 3 4 5 6 7
There are 7 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 = 2.98 (Please notice any zeroes on the end have been removed)
b = 7
Now the whole thing:
2.98 x 107
Step 4
Check your work:
107 = 10,000,000 x 2.98 = 29,800,000
