Question 377357
{{{((2s^(-1)t^3)/(6s^2t^(-4)))^(-3) =((2/6)s^(-1-2)t^(3-(-4)))^(-3)}}}
{{{((2s^(-1)t^3)/(6s^2t^(-4)))^(-3) =((1/3)s^(-3)t^(7))^(-3)}}}
{{{((2s^(-1)t^3)/(6s^2t^(-4)))^(-3) =(3s^(3)t^(-7))^(3)}}}
{{{((2s^(-1)t^3)/(6s^2t^(-4)))^(-3) =27s^(9)t^(-21)}}}
{{{highlight( ((2s^(-1)t^3)/(6s^2t^(-4)))^(-3) =(27s^9)/t^(21))}}}
