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.
They are like terms.
Each variable has an exponent equal to one.
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.
