Answer:

4.3 x 10^6

Explanation:

in scientific notation, numbers are written in the form a x 10^b , where a is the "pre-exponential" part and 10^b is the "exponential part"

to get standard scientific notation move the decimal so there is only one non-zero digit in front of the decimal so 4,300,000 is 4.300,000

answer: 4.3×10^6 :)

explanation:

Why is 4,300,000 written as 4.3 x 106 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 4,300,000 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: 4,300,000

New Number: 4.300000

Step 2

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

New Number: 4 . 3 0 0 0 0 0

Decimal Count: 1 2 3 4 5 6

There are 6 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 = 4.3 (Please notice any zeroes on the end have been removed)

b = 6

Now the whole thing:

4.3 x 106

Step 4

Check your work:

106 = 1,000,000 x 4.3 = 4,300,000
