Answer 1

Answer:

1.304 × $10^{7}$

Step-by-step explanation:

A number in scientific form has the form

a × $10^{n}$

where 1 ≤ a < 10 and n is an integer

Express 13, 040, 000 as a number between 1 and 10

= 1.304 ×$10^{n}$

We require to get the number into its original form.

To do this we require to move the decimal point 7 places right

If left then n < 0 and if right then n > 0

Thus

= 1.304 × $10^{7}$

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 13,040,000 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: 13,040,000

New Number: 1.3040000

Step 2

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

New Number: 1 . 3 0 4 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7

There are 7 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 = 1.304 (Please notice any zeroes on the end have been removed)

b = 7

Now the whole thing:

1.304 x 107

Step 4

Check your work:

107 = 10,000,000 x 1.304 = 13,040,000
