what is scientific notation
What is scientific notation?
  • Scientific notation provides a way to write numbers using powers of ten.
    • Written as a product of 2 factors.
      • The first factor is a number greater than or equal to one BUT less than ten.
      • The second factor is a power of 10.
        • 7,500,000,000,000 = 7.5 x 10

**Scientific Notation lets you know the size of a number without having to count the digits!

About 4,200,000 people visit the Statue of Liberty every year. Write this number in scientific notation.
  • 4,200,000
  • 4.2
  • 4.2 x 10 ⁶
    • Move the decimal point to get a decimal greater than 1 but less than 10.
  • Drop the zeros after the 2.
  • You moved the decimal point 6 places. The number is large. Use 6 as the exponent of 10.
