Frequently Asked Questions
How do you simplify a radical?▾
Factor the number into primes, then move each prime with an even exponent outside the radical in pairs. For example, 50 = 2 × 5², so √50 = 5√2.
What is the square root of a negative number?▾
Real numbers have no real square root of a negative value. In the complex number system the result is an imaginary number, i√|n| (for example √−4 = 2i).
