Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.

An exponential expression is a problem with no answer usually used to answer a question such as, Find the Value ; 2 as a base and 5 as an exponent.; The answer would be 32 because to find the value of an exponent you multiply the number in the base by itself as many times that it says in the exponent.Ex: 2*2*2*2*2=32

The exponential expression a^n is read a to the nth power. In this expression, a is the base and n is the exponent. The number represented by a^n is called the nth power of a.When n is a positive integer, you can interpret a^n as a^n = a x a x ... x a (n factors).

Not necessarily. If the exponent is not an integer then it is not a polynomial.

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.

The exponent for a factor is the number of times that the factor appras in the multiplication. An exponent of 1 is not usually written out. So, 2*2*2*3*3*3*3*5 = 23*34*5

However many variables there are is the exponent. 2x2x2x2x2x2x2 = 2^7 3x3x3 = 2^3 etc.

You can but it has no particular significance.

While this is not the complete definition, an exponential expression has the variable (for example, "x") in the exponent.

Then, if the exponent is a positive integer, the value is 1 multiplied by the base repeatedly, exponent times. If the exponent is a negative integer then it is the reciprocal of the above value.In either case, it is NOT the base multiplied by itself an exponent number of times.

xx = x2 In exponential form the expression becomes x2y. Technically, it would be correct to write x2y1 but, an exponent of 1 is simply omitted in ordinary mathematics.
