true

Not necessarily. Every exponent in the exponent must be a non-negative integer. This is not what you have specified. For example, if n = 3.5, it is not a term in a polynomial expression.

8z^3

The coefficient in algebra is the number before a letter with an exponent on it. The 3 is the coefficient in this example: 3x7

6 is the coefficient of n in this expression.

true

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.

It is 9

7n^5

8z^3

The expression is 5b + 16

The expression is: (4a+b)/(2a-5b)

5b + 15 = 5(b + 3)

Take the exponent and multiply it by the coefficient (or 1 if there is no coefficient) then subract 1 from the exponent. For example, the derivative of 2x^3 is 6x^2 If there is no exponent, for example, 2x the derivative is 2 because the exponent is actually 1 which produces the same coefficient and the exponent 0 meaning there is no x.
