    An nth root. A radical expression involving roots. The radical symbol (√), used to indicate the square root and other roots. Radical of an algebraic group, a concept in algebraic group theory. Radical of an ideal, an important concept in abstract algebra.

    It's not really a specific one, though. It's just the concept of radicals that I don't understand.

    They are an extension of the idea of positive and negative integer exponents generalized to include fractions.

    one rule is that we can NEVER have negative signs inside the radical... that produces an imaginary number.

    when simplifying radical expression treat the radical like a variable:- 3x + 2x = 5x 3 sqrt2 + 2 sqrt2 = 5 sqrt2

    $$\Huge a^{-n}=\dfrac{1}{a^n}$$ this^ extends the idea of positive integer exponents to includes the negative integers, right?

    "the concept of radicals" is to go one more step and let n be a fraction :)
