Square root of 3x-1= 4;5

What d'heck does 4;5 mean? :shock:

Square root of 3x - 1

Your typing above represents this:

\(\displaystyle \sqrt{3} \cdot x \; - \; 1\)

Do you mean the following, instead?

\(\displaystyle \sqrt{3x - 1}\)

If so, then you need to type grouping symbols around the "radicand". The "radicand" is the expression underneath a radical sign.

With grouping symbols, the correct text looks like this:

sqrt(3x - 1)

Or, perhaps, you mean this:

\(\displaystyle \sqrt{3x} \; - \; 1\)

If so, we again type grouping symbols around the radicand 3x.

sqrt(3x) - 1

Please reply with your answers to Denis' and my questions.
