E and F are the only correct ones. Radicals and half powers in the denominator are no-nos.

My choice would be (1/2)x + (3x+9)x^(-1/2)

Use negative powers :thumbsup:

F. You should never leave radicals in the denominator, and you typically should shorten terms as much as possible, although E is a fair guess as well.

LaTeX is the answer

If your teacher cares, he/she must have no life whatsoever. As long as it's readable, it doesn't matter.

You could type it any one of those ways in LaTeX.

How about:

x/2 + 3x^1/2 - 9x^-1/2

 

[otispunkmeyer]

B is the simplest way to write it

 

[Chaotic42]

F seems to be winning.

there is nothing "wrong" with radicals in the denominator - it still equates to the same thing

that being said, most HS teacher do insist that you rationalize it out of there and bring it to the top

in my college level courses, the professors didnt care at all and the graders were adept enough to distinguish equivalent answers
