Please show me how to solve this problem. Solve for X:
ux(the x has an exponent of a) = X

A, must be zero? U, multiplied by X, exponent a, equals a.
Well that can only be zero?
U, equal any integer.. say 1.... U equal any integer say 10, exponent zero, therefore, anything multiplied by zero, is indeed zero, therefore accordingly, a, must equal zero. as
UX exp a = a UX exp 0 = 0

Ux = a where (x is component of a) ; ux = x ; u = 1
therefore : x = a

### What does polynomial function mean?

Let us backtrack so as to better jump.
An algebraic expression may contain one or several algebraic terms, separated by a plus sign or a or a minus and a sign.
Each algebraic term is the product of a constant coefficient and a power of some variable, or the powers of several variables.
Example of an algebraic term 3(x^2)(y^6)....
If the exponents of the various powers are positive integers, the term is called a monomial. In short no square roots, or fractionary powers of the variables appear in monomials. Thus 2/x, 3SQRT(x), or 1/x^5 are not monomials.
Finally, a polynomial is an algebraic expression made up of one or more monomials.
Example P(X)=(1/3)X^7-(SQRT(5)*X^4+ 16X-25 is a polynomial of degree 7 in the indeterminate/variable X
Q(X,Y)= 3(X^3)*Y^2 + 4X-5Y+10 is a polynomial of degree 5 in the variables X and Y.

### Subtracting monomials

Hi there,

Remember that the SHARP calculator does not solve algebra.
But some tips for adding and subtracting monomials include:
Group all the terms that are like terms (they have the same variables and exponents. Make sure that you move them with the sign in front of them (dont lose your minuses).
Add or subtract just the numbers in front of the terms and leave the variables exactly as they are when you write down the answer.

### X^-2/5=16 what is x?

Hi there, If the problem is x^(-2/5)=16 then x is 1/1024, -1/1024 - it can be either of those answers because of one of the general rules of exponents. This can be solved using Algebra. Isolate for x by -2/5sqrt both sides. -2/5 sqrt 16 = 1024 or -1024. If you would like a step by step process, let me know! Alex

### I just got the TI-Nspire. I'd like to solve a problem with undefined variables using Negative Exponent and things like the Expanded Power Rule. The Nspire will not let me store "x" as a variable. How...

You need the TINspire CAS (Computer Algebra System) to do symbolic manipulations. The Blue TINspire (with TI 84 keyboard) can only perform numerical computations.
If you use variables, the calculator will assign the numerical value stored in the variable.

### Can it solve 8^x=4 ???

Hi,
You can use algebra to solve it.
Use the fact that 4 =2^2 and 8=2^3 and substitute in the equation
(2^3)^x =2^(3*x)
Then 2^(3*x)=2^2
By equating the exponents
3x=2 and x=2/3

Using the solve( function
With the calculator physical keys between square brackets, and the SHIFTed or ALPHA keys between parentheses, type in the following
8 [^ ] [ALPHA] [ ) ] (X) [ALPHA][CALC] ( =) 4 [SHIFT][CALC] (SOLVE)

Once the foregoing command entered press [=]
Display shows Solve for X on top line and probably 0.000 on bottom line.
Press [.] 5 to give 0.5 as a guess for the value of x
After a moment the calculator returns with the solution.
The display shows three lines
1st Line: 8[^] X =4
2nd Line: X= 0.66666666
3rd Line : L-R =0.

Your solution is 0.6666666. In fact the exact solution is 2/3.

Hope it helps.
Thank you for using FixYa and for rating this solution.

### 66-(-6)x6-(-6)=

The order of operations of math is:
1. Parentheses
2. Exponents
3. Multiplication and Division

So for the problem you posted:
1. Remove the parentheses. The minus signs of -(-6) cancel and can be rewritten as +6. So the problem can be rewritten as 66+6x6+6.
2. Solve the 6x6 part first. Now the problem is 66+36+6,
3. Solve the arithmetic from left to right.

### Entering a problem

Hi Loringh,
see, high exponents are +ve powers, while low exponents are -ve powers.
e.g. for 1200000=1.2X10^6=1.2E+6 (high exponents)
for 0.0000000012=1.2X10^-9=1.2E-9 (low exponents)
I think so easy ?

Thanks

### The dreaded Cassio fx 115MS S-V.P.A.M.

I played with my calculator, and discovered that the "EXP" function does not play well with variables using the "CALC" function. Instead of EXP, use ' x 10 ^ C ' or whatever instead.
