Question 334851
Power to a power rule say 'multiply them'. 
So do that first.
Then move the remaining 'negative' powers and make them postives (if negative is in the numerator, move to the denominatopor and change the sign or vice-versa)
{{{ (((m^(-2) n^3*p^4)^(-2) )* (mn^(-2) p^3)^4) / (((mn^(-2) p^3)^(-4))*(mn^2 *p)^(-1)) }}} 
{{{ (m^4* n^(-6)*p^(-8) * m^4n^(-8)* p^12) / (m^(-4)*n^8* p^(-12)*m^(-1)*n^(-2) *p^(-1)) }}}
{{{ (m^8* n^(-14)*p^4) / (m^(-5)*n^6* p^(-13)) }}}
{{{ (m^13* p^17) / n^20 }}}
