What is defined as the scientific notations?

Scientific notation is a method of expressing extremely large or extremely small numbers.

  • When a quantity between 1 & 10 is multiplied by a power of 10, it is composed in scientific notation.
  • 650,000,000, for example, can be composed in scientific notation as 6.5× 10⁸.
  • The scientific notation system relies on powers of ten. The coefficient is the first number, 1.23.

For the given question;

  • Diameter of the black hair is 2.4×10⁻³ inch.
  • Diameter of the red hair is 0.001 inch.

Convert the decimal value 0.001 in scientific notations;

= 0.001 inch

= 1×10⁻³ inch

Now, calculate the difference;

Difference in diameter = Black hair diameter - Red hair diameter

Difference in diameter =  2.4×10⁻³ - 1×10⁻³

Difference in diameter = 1.4×10⁻³

Therefore, the value of the difference in the diameter of red and black hair is found as 1.4×10⁻³.
