48^5*2^(-8)=3^5*16^5*2^(-8)=3^5*(2^4)^5*2^(-8)=3^5*2^20*2^(-8)=3^5*2^12
mianownik
72^(-7)*24^16*16^(-4)*2^(-2)=8^(-7)*9^(-7)*3^16*8^16*(2^4)^(-4)*2^(-2)=
=(2³)^(-7)*(3²)^(-7)*3^16*(2³)^16*2^(-16)*2^(-2)=
=2^(-21)*3^(-14)*3^16*2^48*2^(-16)*2^(-2)=2^(-21+48-16-2)*3^(-14+16)=
=2^9*3²
toz 3^5*2^12/2^9*3²=3^(5-2)*2^(12-9)=3³*2³=27*8=216
