5000000 in Scientific Notation

5000000 in scientific notation

5{,}000{,}000 = 5 \times 10^{6}

5000000 in scientific notation is 5 × 10⁶ – the decimal point moves 6 places to the left, so the power of ten is 6.

  • E-notation: 5E+6 (calculators, Excel, programming)
  • Engineering notation: 5 × 10⁶ (the power is a multiple of 3)
  • Said aloud: five times ten to the power of six
  • Significant figures: 1 to 7 (the zeros at the end may or may not count)
  • Order of magnitude: \displaystyle 10^{6}
  • In the Indian system: 50,00,000 – fifty lakh
  • In words: five million

Step-by-step solution

The problem

\text{Write } 5{,}000{,}000 \text{ in scientific notation}
1

Find the coefficient

a = 5

Scientific notation is \displaystyle a \times 10^{n} with \displaystyle 1 \le a < 10. Put the decimal point just after the first non-zero digit (5); the zeros at the end only hold places, so they are left out.

2

Count the places the decimal point moves

  1. 5,000,000
  2. 500,000
  3. 50,000
  4. 5000
  5. 500
  6. 50
  7. 5

From \displaystyle 5{,}000{,}000 to \displaystyle 5 the decimal point moves 6 places to the left.

3

Choose the sign of the exponent

n = 6

The number is 10 or more, so the point moved left and the exponent is positive: each place left divides by 10, and \displaystyle 10^{6} multiplies it back.

4

Write it in scientific notation

5{,}000{,}000 = \textcolor{#0b5c56}{5 \times 10^{6}}

Check

5 \times 10^{6} = 5 \times 1{,}000{,}000 = 5{,}000{,}000 \;\checkmark

Multiply the coefficient by the power of ten to get back the number.

The digits 5 at other powers of ten

Only the power changes when the decimal point moves – each place left is one more step of ten.

Frequently asked questions

Is 50 × 10⁵ the same as 5 × 10⁶?

It has the same value, but it isn’t scientific notation: the number in front must be at least 1 and less than 10, and 50 is not. Move the point one more place and add 1 to the power: 5 × 10⁶.
