    Study Notes

    Exponentiation and Root Extraction

    Power of a Product

    • The power of a product is the product of the powers of the individual factors.
    • Formula: (ab)^n = a^n * b^n
    • Example: (2x)^3 = 2^3 * x^3 = 8x^3

    Power of a Power

    • The power of a power is the power raised to another power.
    • Formula: (a^n)^m = a^(n*m)
    • Example: (2^3)^2 = 2^(3*2) = 2^6 = 64

    Zero Exponent

    • Any non-zero number raised to the power of zero is equal to 1.
    • Formula: a^0 = 1
    • Exception: 0^0 is undefined in standard arithmetic, but may have specific values in certain mathematical contexts.

    nth Root

    • The nth root of a number is a value that, when raised to the power of n, gives the original number.
    • Formula: x = nth root of a ⇔ x^n = a
    • Example: x = 3rd root of 27 ⇔ x^3 = 27
    • Note: The nth root of a number can be positive or negative, depending on the value of n.
