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