Answer 1

[(-9)⁵⁴:3¹⁰⁶-8¹¹²:4¹⁵⁰+(-5)⁹²:(5⁹)⁵]:(9-2³⁶+5⁴⁷)=
=[(9)⁵⁴:3¹⁰⁶-2³³⁶:2³⁰⁰+5⁹²:5⁴⁵]:(3²-2³⁶+5⁴⁷)=
=(3¹⁰⁸:3¹⁰⁶-2³⁶+5⁴⁷):(3²-2³⁶+5⁴⁷)=
=(3²-2³⁶+5⁴⁷):(3²-2³⁶+5⁴⁷)=1

{[(-27)³¹]⁵:(+81)⁷⁵ × [(-9)¹⁵]⁷-[(-25)¹²]⁵×125⁹}:(3³⁷⁵-5¹⁴⁷)=
={(-3⁹³)⁵:(3⁴)⁷⁵ × [-(3²)¹⁵]⁷-[(-5²)¹²]⁵×(5³)⁹}:(3³⁷⁵-5¹⁴⁷)=
={[(-3)⁴⁶⁵:3³⁰⁰ × [-(3²¹⁰)-[5²⁴]⁵×5²⁷}:(3³⁷⁵-5¹⁴⁷)=
=[(-3)¹⁶⁵ × (-3²¹⁰) -5¹²⁰×5²⁷}:(3³⁷⁵-5¹⁴⁷)=
=(3³⁷⁵ -5¹⁴⁷):(3³⁷⁵-5¹⁴⁷)=1
