Question 134138
{{{((3^-3u^2w^-5)/(6^-1u^-1w^-2))^-2}}}
:
Combine exponents of like terms so the exponents will be positive
{{{((6*u^(2+1))/(3^3w^(-2+5)))^-2}}}
:
{{{((6*u^3)/(3^3w^3))^-2}}}
:
{{{((3^3w^3)/(6*u^3))^2}}}; inverting get rid of neg 
:
{{{((27w^3)/(6*u^3))^2}}}
:
Square everything multiply exponents:
{{{(729w^6)/(36u^6)}}} = {{{(81w^6)/(4u^6)}}}; reduce the numerical fraction
