Respuesta :

Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).

We split up the radicand into perfect squares.  Once we do, we take out the things that were squared:
[tex]3\sqrt{27x^{18}} = 3\sqrt{3\times3\times3x^2x^2x^2x^2x^2x^2x^2x^2x^2x^2} = 3*3*xxxxxxxxx\sqrt{3} [/tex]
[tex]=9x^9\sqrt{3}[/tex]
