Scientific Notation to Number

What is the Written Out Form of 4e-9? Convert a scientific e notation value to a written out form. Scientific notation is a way of expressing numbers that are very large or very small in a more compact and convenient form. The basic idea is to use powers of 10 to represent the magnitude of the number, while preserving the significant digits. In scientific notation, a number is expressed as a coefficient (a number between 1 and 10) multiplied by a power of 10.

To convert any scientific notation to a decimal number follow those steps, which is given below-

  1. Separate scientific notation value into two parts by the "e".
  2. The first part is before the "e" which is called "coefficient" and the second part is after the "e" which is called "exponent", "e" is called as "10 to the power".
  3. To calculate, multiply "coefficient" by "10 to the power" of "exponent" (Example: 4×10-9).
  4. Calculate the equation.

For calculation, here's how to Convert 4e-9 to Number using the formula above, step by step instructions are given below

  1. Here is the separated name of the scientific notation value 4e-9.
    Where,
    4 = coefficient;
    e = 10 to the power;
    -9 = exponent;
  2. To convert, multiply "coefficient" by "10 to the power" of "exponent". Like this (4 × 10 ^ -9)
    4 × 10-9
  3. After calculate the equation.
    0.000000004
