Answer 2

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 200 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: 200

New Number: 2.00

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 2 . 0 0

Decimal Count: 1 2

There are 2 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 (Please notice any zeroes on the end have been removed)

b = 2

Now the whole thing:

2 x 102

Step 4

Check your work:

102 = 100 x 2 = 200
