Study Notes

Exponents and Powers

  • An exponent is a small number that tells how many times a base number should be multiplied by itself.
  • In mathematics, the term 'power' refers to the operation of raising a number to an exponent.

Exponent Notation

  • The notation a^n represents a raised to the power of n, where a is the base and n is the exponent.
  • For example, 2^3 represents 2 multiplied by itself 3 times, i.e., 2 × 2 × 2 = 8.

Calculating Powers

  • The result of 5^2 is 5 multiplied by itself 2 times, i.e., 5 × 5 = 25.
  • In the expression 3^4, the number 4 represents the exponent, which means 3 is multiplied by itself 4 times, i.e., 3 × 3 × 3 × 3.

Special Case: Any Number to the Power of 0

  • The value of 2^0 is 1, since any number raised to the power of 0 is equal to 1.
