What is 40000 as a scientific notation?

4 x 104 Forty thousand
40,000 = 4 x 104 Forty thousand: the distance around the Earth at the equator (in km). 4,000 = 4 x 103 Four thousand: The circumference of Pluto (in km). As you can see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form.

How do you write 300000000 in scientific notation?

Large and Small Numbers

  1. The speed of light is approximately 300,000,000 meters per second.
  2. Using scientific notation,300,000,000 m/sec can also be written as.
  3. 3 x 100,000,000.
  4. or in the shorter form,
  5. 3 x 108,
  6. where 8, the exponent, is the number of zeros.

How do you write numbers in scientific notation?

To write in scientific notation, follow the form. where N is a number between 1 and 10, but not 10 itself, and a is an integer (positive or negative number). You move the decimal point of a number until the new form is a number from 1 up to 10 (N), and then record the exponent (a) as the number of places the decimal point was moved.

How do you convert scientific notation to standard form?

To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.

What are the steps of scientific notation?

Steps in Writing Decimal Numbers into Scientific Notation STEP 1: Identify the initial location of the original decimal point. STEP 2: Identify the final location or “destination” of the original decimal point. STEP 3: Move the original decimal point to its final location. STEP 4: Write “c” multiplied by some power of base 10.

Why would I need to use scientific notation?

The primary reason why scientific notation is important is that it allows us to convert very large or very small numbers into much more manageable sizes. When these numbers are in scientific notation, it is much easier to work with them.
