This is what you are probably hoping to express (which took a few hours after first seeing the posting):

2*root(4,36)-3*root(6,216)+sqrt(216)

2%2Aroot%284%2C36%29-3%2Aroot%286%2C216%29%2Bsqrt%28216%29, rendering as similar to normal notation.

2%2Aroot%284%2C36%29-3%2Aroot%286%2C216%29%2Bsqrt%28216%29

Assuming only positive values from any radical,

2%2A36%5E%281%2F4%29-3%2Aroot%286%2C54%2A4%29%2Bsqrt%2854%2A4%29

2%2A%286%5E2%29%5E%281%2F4%29-3%2Aroot%286%2C2%5E3%2A3%5E3%29%2Bsqrt%282%5E3%2A3%5E3%29

2%2A6%5E%281%2F2%29-3%2Aroot%286%2C6%5E3%29%2Bsqrt%286%5E3%29

2%2Asqrt%286%29-3%2A6%2B6%2Asqrt%286%29
