Answer 2

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
