Question 305527
{{{ x = -(27/125)^(-4/3) }}}



{{{ y = (x)^(-z) }}}
{{{ y = 1/((x)^(z)) }}}


{{{ y1 = (x1)^(m/n) }}} = n root of x1 raised to the power m. So first we get rid of the negative sign:
{{{ x = -(27/125)^(-4/3) }}}
{{{ x = (-1)/((27/125)^(4/3)) }}}
now use the m/n exponent information
{{{ x = (-1)/((3/5)^(4)) }}}
{{{ x = (-1)/(81/625) }}}
{{{ x = (-625)/81 }}}
