Zoee: Here's a case where parentheses are badly needed to clarify this post. I am unsure of whether you mean 4*sqrt(9)/2x, or 4*sqrt(19/2)/ x or something else.

All I can do here is work backwards from the given possible answer "sqrt(9x)". That could be simplified to "sqrt(9)*sqrt(x)", which equals 3*sqrt(x). Not very helpful.

So, Zoee, at this point I recommend that you share an image of the original problem. Could you take and share a screen shot? Only with the original problem in mind could I help you meaningfully as you try to express the problem and its possible solutions.

Answer with explanation:

We have to find equivalent expression of


\rightarrow4* \sqrt{9^{(1)/(2)}}* x\\\\\rightarrow4* (9^{(1)/(2)})^{(1)/(2)}}* x}\\\\\rightarrow 4 *{9^{(1)/(4)}}* x}\\\\\text{Used the Identity}(a^b)^m=a^(bm)

Two expression are said to be equivalent, if we replace the variable by some constant value , the Numerical value of Original expression and the Numerical value of Equivalent expression are same.
