Question 78050

{{{3sqrt(-8/27)}}}=

{{{3sqrt((-2*4)/(3*9))}}}=
{{{3(2/3)(i)sqrt(2/3)}}}= (note: {{{i=sqrt(-1)}}}

{{{(2i)sqrt(2)/sqrt(3)}}}  multiply numerator and denominator by{{{sqrt(3)}}}

{{{(2i)sqrt(2*3)/3}}}=
{{{(2i)sqrt(6)/3}}}

Actually, we could us a calculator and reduce it more but I don't think that's necessary

Hope this helps----------------ptaylor
