A radical expression contains a root symbol (√). The nth root of x: ⁿ√x = x^(1/n). Square roots (n=2) are most common. Simplifying radicals means removing perfect square factors from inside the radical.
Trin-for-trin guide
- 1√(ab) = √a × √b (product rule for radicals)
- 2√(a/b) = √a / √b (quotient rule)
- 3Simplify: √72 = √(36×2) = 6√2
- 4Rationalize denominator: 1/√2 = √2/2
