you CAN have a variable as an exponent.
When multiplying a variable with an exponent by a variable without an exponent, you add the exponent of the first variable to the exponent of the second variable (which is considered to be 1). For example, if you multiply (x^2) by (x), the result is (x^{2+1} = x^3). This rule applies to variables with the same base.
Yes, you can multiply a variable with an exponent by a variable without an exponent. When you do this, you simply add the exponents of the same base. For example, if you multiply (x^2) by (x), the result is (x^{2+1} = x^3).
multiply
That is the correct spelling of "exponent" (an advocate, or the numerical power to which a number or variable is raised)
XnThat is an exponent.
the variable's exponent
No. An expression can have a variable exponent (for instance, 2 to the power x, or x to the power y), but that is no longer a polynomial.
Whenever you see a variable (letter) without any exponent, it's exponent is 1.

Depends on the problem.
An expression is non polynomial if it has : negative exponent fractional exponent variable exponent in the radicand
XnThat is an exponent.
1
2.
When you take the square root of a variable raised to an exponent, you divide the exponent by two. For example the square root of x^4 is x^2, because x^2 x x^2 =x^4.
