A students work to simplify a radical is shown below. Select the statemmebt which best applies to rhe sample mathematical work
Alik [6]

Answer:

D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further.

Step-by-step explanation:

If you add all the exponents of y in first line then we get

4+4+4+4+4+3=23

Which is same as the exponent in original problem.

So first line is good.

Since it is 4th root so each y^4 will turn into y when it moves out of the radical so final answer is correct.

Hence correct choice is "D. The work shown above is correct, and y^5\sqrt[4]{y^3} may not be simplified further." is the correct answer.

If p(x) = x + 3, then what is the value of p(x) + p( - x)?
garik1379 [7]

Answer:

p(x) + p(-x) = 6 is

Step-by-step explanation:

In this question, we are tasked with calculating what p(x) + p(-x) will be

From the question, we know that p(x) = x + 3

Then p(-x) will be p(-x) = -x + 3

Thus p(x) + p(-x) = x + 3 -x + 3

p(x) + p(-x) = 3 + 3 = 6
