which is does not belong to the group?

c.[tex] \frac{4}{ \sqrt{a} } [/tex]



Sagot :

Answer:

[tex] \frac{4}{ \sqrt{a} } [/tex]

Step-by-step explanation:

The 4th choice is the odd one out because it is the only non-monomial among the group. This choice is the only one with a denominator containing a variable.

Because of this, if we were to equate all the choices into y, and change a into x, only the fourth choice will not have the set of real numbers as its domain.

Hope this helps!
