square root: evaluate [4x^3 12x^a] ÷ [6x^2 12x^0]

I need to know how to Evaluate: [(4X³) x (12Xª)] ÷ [(6X²) x (12X°)]
 
It would have been different if the instructions had been something like "simplify", but without values for x or a, there is no way to evaluate (find the numerical value for) this expression. Sorry.

what about using the basic exponential term multiplication relations. then you dont have to add or subtract any like terms...so then i could just foil this problem to come up with a solution?
 
Zhyia, you have posted so many really simple and elementary algebra problems without showing any effort on your own. You have used the wrong terms in the giving instructions. No reliable text or teacher would ask anyone to evaluate the expression you posted above.

Now, you reply to this by show us what you can do in reducing the expression to its simplest terms. This a simple exercise in applying laws of exponents.
 
funny...since its so easy. I will review our textbook and get back to you with an answer to this problem, but as far as how i posted the wrong term... i posted the question exactly how it was given to me by my professor. It specifically says evaluate the problem.

what's to FOIL? there are no binomials in the expression.

\(\displaystyle \frac{(4x^3)(12x^a)}{(6x^2)(12x^0)} =\)

\(\displaystyle \frac{48x^{3+a}}{72x^{2+0}} =\)

\(\displaystyle \frac{48}{72} x^{(3+a)-(2+0)} =\)

\(\displaystyle \frac{2}{3} x^{a+1}\)

that's as far as one can simplify the original expression ... it cannot be "evaluated".

I find that almost impossible to believe!
So sort of professor are you talking about?
Surely not a mathematics professor!
 
you have issues...this site is suppose to help people not create more problems...maybe its just you who has the problem anyway. Do you find that hard to believe?

I agree with everything Pka has said, zhyia. I knew something was "odd" about you. You don't post complete problems and it is very hard to understand anything you type. You're the one with issues, not us.

So... maybe English isn't your professor's first language...? Because, as has been explained at length, there is nothing to "evaluate" here. You can only "simplify" (though "FOIL" would not come into play at all).

If what you say is accurate, then I would strongly recommend that you schedule a conference with an administrator in the mathematics department, because your "professor" doesn't know basic (grade-school) terminology and is clearly not teaching you the material with any competence at all.

Perhaps if you switch to another section now (the summer semester just started, right?), you may be able to learn the material you've missed thus far, and get caught up in time for the final.

Good luck.

Eliz.
