Simplifying Polynomials...?
Back and still doing a review from two years ago. Does anyone have some links or explanations on how to solve polynomials?
Here's one of the problems, a * indicates there is a power
2x(x*)*
the first * is the 3rd power, the second is the 4th power

They are asking you to "simplify" And what that really means it to write this expression using less pencil lead. Remember as well, that the exponent belongs just to the guy in front, and for your second exponent, it is only to the set of ( ).Remember that no exponent on an x means that it really has a phantom 1.
So your first step is to solve the (x^3)^4 And that is called a power of a power, so you multiply it to x^12
Now you have 2x(x^12) . There now is that rule called "when you multiply bases you add the exponents". The simplification of this then is 2x^13
See why?
Source(s): math teacher Your first respondent changed this expression to an equation... and that is not what you are asked to do... there is no 8, and no equal sign. All you are asked to do is make it simpler... - Anonymous1 decade ago
2x* *=8
i don't know any sites but if you googleit you will probably be able to find a lot.
--All you need to do is multiply all the variables together. REMEMBER when you multiply variables with exponents you add the exponents together =), good luck remembering everything else...i wouldn't be able to do a review from 2yrs ago -.-
