<pre>
{{{8*sqrt(12)}}}{{{""+""}}}{{{3*sqrt(27)}}}{{{""-""}}}{{{sqrt(48)}}}

{{{8*sqrt(4*3)}}}{{{""+""}}}{{{3*sqrt(9*3)}}}{{{""-""}}}{{{sqrt(16*3)}}}

{{{8*sqrt(4)*sqrt(3)}}}{{{""+""}}}{{{3*sqrt(9)*sqrt(3)}}}{{{""-""}}}{{{sqrt(16)*sqrt(3)}}}

{{{8*2*sqrt(3)}}}{{{""+""}}}{{{3*3*sqrt(3)}}}{{{""-""}}}{{{4*sqrt(3)}}}

{{{16*sqrt(3)}}}{{{""+""}}}{{{9*sqrt(3)}}}{{{""-""}}}{{{4*sqrt(3)}}}

{{{(16+9-4)*sqrt(3)}}}

{{{21*sqrt(3)}}}
