For the given algebraic fraction, complete parts a and b. 57x^5/19x^2 a. simplify the algebraic fraction. in your final answer, include all of your work. b. determine the excluded value(s) of the variable. in two or more complete sentences, explain how you determine the excluded value and why it cannot be a possible value for the variable.

(3•19x5) Simplify ———————— 19x2 Dividing exponential expressions :

 3.1    x5 divided by x2 = x(5 - 2) = x3

Canceling Out :

 3.2      Canceling out  19  as it appears on both sides of the fraction line 

Final result : 3x3

(ab)/(cd)=(a/c)(b/d)
and
(x^m)/(x^n)=x^(m-n)

so
(57x^5)/(19x^2)=(57/19)(x^5/x^2)=(3)(x^5-2)=3x^3

excluded values are the factors factored out

57/19=(19*3)/(19)
excluded value is 19

for
(x^5)/(x^2)=(x^2*x^3)/(x^2)
excluded value is x^3

so

excluded values are 19 and x^3

Part A.

Party B. Excluded value 19

Step-by-step explanation:

Given :

Part A. Simplify the algebraic fraction.

Step 1- Write the expression

Step 2- In division same base powers get subtracted

Step 3- Divide 57 by 19

Therefore,

Part B.  Determine the excluded value(s) of the variable. In two or more complete sentence, explain how you determine the excluded value and why it cannot be possible value for the variable.

Excluded value of the variable is 19

because, 19 comes on both the side as the factor of 57 is 19×3

So we can write 57 in the form of  19×3 and by divisor of 19 it cancel out.

So, automatically 19 has to be cancel out in any situation you can also see in above steps.

Therefore, it cannot be possible value for the variable.

A) you have to do it separably so do 57 divided by 19 first which is 3. Then you can do x^5 divided by x^2. When you are dividing indices you take them away so you are doing 5-2 which is 3 So the answer is 3x^3.
b) idk how to do that sorry 

First off the answer to the problem is 3x^7 Multiply 3 3 by −7 - 7 to get −21 - 21 . Move all terms containing x x to the left side of the equation. Since 3x 3 ⁢ x contains the variable to solve for, move it to the left side of the equation by subtracting 3x 3 ⁢ x from both sides. Subtract 3x 3 ⁢ x from 3x 3 ⁢ xto get 0 0
hope it helped =)

Now u can mark his as brainliest:)

Sorry dude I just need point
