The product of four and a number would be algebraically written as 4n, or whatever variable equals the number. In this case, n = number. It would not be written n4, nx4, 4xn, 4*n or n*4, although n4 and the ones with stars may be accepted by a teacher.
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.
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).
Multiplying a number by itself. Four squared = 4 x 4 = 16 Also written 42
