The right option is; [D] scientific notation

Kevin is describing scientific notation.

Scientific notation is a special method of writing numbers (values) that are very small or very large. Scientific notation is used when a number between 1 and 10 is multiplied by a power of 10. For example, 800 can be written in scientific notation as 8 x 10^2.


Answer : The correct option is, (D) scientific notation

Explanation :

  • Scientific notation : It is a way of writing the smaller and larger numbers. It is written as the product of a number between 1 and 10 and a power of 10.

        For example : 550,000,000 can be written in scientific notation as          [tex]5.5\times 10^{8}[/tex]

  • Significant figures : It is defined as the minimum number of digits are needed to express a number in scientific notation without a loss of accuracy.
  • Common logarithm : It is defined as the base 10 logarithm is known as the common logarithm.

        It is represented as, [tex]\log_{10}x=\log x[/tex]

  • Multiplication factors : It is defined as the number that is multiplied by another to give a product.

        For example : [tex]5\times 4=20[/tex] in this, 5 and 4 are the multiplication factors.

Hence, the Kevin describing is scientific notation.
