{{{(9t^5v^8)^(1/3)*(6tv^4)^(1/3) =(54*t^(5+1)*v^(8+4))^(1/3)}}}
{{{(9t^5v^8)^(1/3)*(6tv^4)^(1/3) =(54t^6v^12)^(1/3)}}}
{{{(9t^5v^8)^(1/3)*(6tv^4)^(1/3) =2^(1/3)*(27)^(1/3)*(t^(6/3))*(v^(12/3))}}}
{{{(9t^5v^8)^(1/3)*(6tv^4)^(1/3) =2^(1/3)*3*t^2v^4}}}
{{{(9t^5v^8)^(1/3)*(6tv^4)^(1/3) =3*2^(1/3)t^2v^4}}}
