3√45-5/2√1/3+4√3

Trying to parse the usual sloppiness with parentheses, I get

3√45-(5/2)√(1/3)+4√3
3√(9*5) - 5/2 * 1/√3 + 4√3
9√5 - 5/(2√3) + 4√3
9√5 - 5√3/6 + 4√3
9√5 + 7/2 √3

If I interpreted it wrong, try typing in your expression at wolframalpha.com

It will show how it read your input, and you can insert parentheses until it agrees with your intent.
