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 674,000 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: 674,000

New Number: 6.74000

Step 2

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

New Number: 6 . 7 4 0 0 0

Decimal Count:   1 2 3 4 5

There are 5 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 = 6.74 (Please notice any zeroes on the end have been removed)

b = 5

Now the whole thing:

6.74 x 105

Step 4

Check your work:

105 = 100,000 x 6.74 = 674,000
