Answer:

A: 6.94 x 102

Step-by-step explanation:

Why is 694 written as 6.94 x 102 in scientific notation?

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 694 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: 694

New Number: 6.94

Step 2

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


New Number: 6 . 9 4

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 = 6.94


b = 2


Now the whole thing:


6.94 x 102


Step 4

Check your work:


102 = 100 x 6.94 = 694
