  1. 2. the number under a radical symbol (√)
  2. 6. the process of taking a complex conjugate of a complex number, complex matrix, etc., or of performing a conjugation move on a knot.
  3. 7. result of f() is sent through g()
  4. 9. the relation that occurs when the order of the elements is switched in the relation
  5. 13. an equation in which a variable is under a radical
  6. 15. A number or symbol, often written as a subscript or superscript to a mathematical expression, that indicates an operation to be performed, an ordering relation, or a use of the associated expression.
  7. 16. applying one function to the results of another
  8. 17. A mathematical expression containing a square root and an inequality.
  9. 18. f(x) = √x (usually just referred to as the "square root function") is a function that maps the set of non-negative real numbers onto itself.

  1. 1. Contains a radical expression with the independent variable (usually x) in the radicand
  2. 3. A solution to an equation that seems to be right, but when we check it (by substituting it into the original equation) turns out NOT to be right.
  3. 4. the process by which a fraction containing radicals in the denominator is rewritten to have only rational numbers in the denominator
  4. 5. radicals that have the same root number AND radicand
  5. 8. a function that undoes the action of the another function
  6. 10. the sign √, which indicates the square root of the number following (or a higher root indicated by a preceding superscript numeral).
  7. 11. An expression with an inequality.
  8. 12. The unique nonnegative square root of a nonnegative real number
  9. 14. The number that must be multiplied times itself n times to equal a given value
