what is the answer to 3 square root 27 x6

OR the asker could mean;

$$3\sqrt{27}\times6\\\\ =3\times 3\sqrt3\times6\\\\ =54\sqrt3\\\\ \approx 93.53$$

93.5307436087 do 3 squarared 27 then do times 6

You have to specify what you mean here... this could be 

(³√27) * 6

or

³√27*6

Depending on which problem you're trying to solve, your answer would be

(³√27) * 6 = 3*6 = 18

or

³√27*6 = ³√162 = 5.451361778496419

I'm thinking your probably looking for the first answer.
