An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. In the expression 4x^2 (four x squared) the four is the coefficient and the 2 is the exponent.
2 x 2 x 2 x 2 x n = 8n
