Question 357320
{{{((2s^-1t^3)/(6s^2t^-4))^3=(2s^-1t^3)^3/(6s^2t^-4)^3}}}
{{{((2s^-1t^3)/(6s^2t^-4))^3=(8s^(-3)t^9)^3/(216s^6t^(-12))}}}
{{{((2s^-1t^3)/(6s^2t^-4))^3=(8/216)s^(-3+6))t^(9-12)}}}
{{{((2s^-1t^3)/(6s^2t^-4))^3=(1/27)s^(3))t^(-3)}}}
{{{((2s^-1t^3)/(6s^2t^-4))^3=highlight(s^3/(27t^3))}}}
