a³ + b³ = (a + b)(a² - ab + b²)
What is the formula for the Difference of Cubes?
a³ - b³ = (a - b)(a² + ab + b²)
What is the outcome when dividing exponents with the same base?
a^m / a^n = a^(m - n), a ≠ 0
What does the Power of a Power rule state?
(a^m)^n = a^(m × n)

a⁰ = 1, a ≠ 0
What does a negative exponent represent?
a^(-n) = 1 / a^n
How is a radical expressed as a fractional exponent?
ⁿ√(a^m) = a^(m/n)
What is the square root of a squared term?
√(a²) = |a|
How do you express the square root of a product?
√(ab) = √a × √b
What is the quotient of square roots rule?
√a / √b = √(a/b)
What does the Log of a Product rule state?
logb(xy) = logb(x) + log_b(y)
What is the formula for the Log of a Quotient?
logb(x/y) = logb(x) - log_b(y)
How do you express the Log of a Power?
logb(x^n) = n × logb(x)
What is the result of multiplying rational expressions?
(a/b) × (c/d) = (ac)/(bd)
What is the result of dividing rational expressions?
