Which of the following cannot be a part of a rational expression?

A rational expression is anything of the form P/Q where both P and Q are polynomials. The value of Q cannot be zero. Recall that polynomials cannot have square roots of variables in them. So we cannot have something like .

You can think of as . The non-whole number exponent is not allowed with polynomials. Only positive whole numbers are allowed as exponents when it comes to polynomials.

Side note: choice C can be written as 4x^0 which is a polynomial (specifically it is a monomial of degree 0, similar to how choice A is as well).

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

darn right!
