Answer :
Answer:
8 times 10 cubed
Step-by-step explanation:
Move your decimal over until what you have one non-zero number left of your decimal point. The number of places left you move the decimal point left is the exponent to your answer.
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
Calculating scientific notation for a positive integer is simple, as it always follows this notation:
a x 10b
Follow the steps below to see how 8,000 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: 8,000
New Number: 8.000
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 8 . 0 0 0
Decimal Count: 1 2 3
There are 3 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 = 8 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
8 x 103
Step 4
Check your work:
103 = 1,000 x 8 = 8,000
