Answer 1

d)[(2^8)^3:8:(2^6+2^6)-16^3•4^5:2^8]:2^12+2=
=[(2^24:2^3:2^7-2^12•2^10:2^8]:2^12+2=
=[(2^14-2^14]:2^12+2=
=[(2^14-2^14]:2^12+2=
=0:2^12+2=2

c)9^23:(3^44+3^20•27^8+3^60:81^4)-2^20:(2^19+2^19)=
=3^46:(3^44+3^20•3^24+3^60:3^16)-2^20:2^20=
=3^46:(3^44+3^44+3^44)-1=
=3^46:[3^44(1+1+1)]-1=
=3^46:(3^44×3)-1=
=3^46:3^45-1=
=3^1-1=
=3-1=2
