### Not acceptable?

I think it's a vast overstatement to say that the forms

sqrt(1.8) and sqrt(5/3)

are not acceptable. In fact, I think that in many situations they should be preferred. While I concede that it's handy for an instructor to be able to immediately glance at a solution and see whether or not it agrees with the one standard answer, I think the pedagogical cost of arbitrarily dictating that other forms are not acceptable is too high.

I would rephrase the entry as presenting a procedure for putting expressions like the ones above into a standard form, without issuing any judgment on which is better.

### Re: Not acceptable?

You may be right -- I will alter the expression.
