you CAN have a variable as an exponent.
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.
An exponent coefficient typically refers to the numerical factor that multiplies a variable raised to a power in an algebraic expression. For example, in the expression (3x^2), the number 3 is the coefficient, while (x^2) indicates that the variable (x) is raised to the exponent of 2. The coefficient provides the scaling factor for the variable's exponential term.
They are like terms.
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.
multiply
Yes.
That is the correct spelling of "exponent" (an advocate, or the numerical power to which a number or variable is raised)
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.
