Study Notes
Radicals and Rational Exponents
-
x²: Represents a variable x raised to the power of 2, indicating it is multiplied by itself.
-
x^(4/3): Indicates x raised to the four-thirds power, a rational exponent reflecting both multiplication and a cube root.
-
x^(1/9): Signifies the ninth root of x, represented as a rational exponent.
-
x^(1/2): Equivalent to the square root of x, illustrating a common radical form.
-
x^(1/3): Represents the cube root of x, a typical radical expression.
-
1: The multiplicative identity, representing no change when multiplied by any number.
-
x: The variable itself, fundamental in algebra and expressing unknown quantities.
