= [3^90+(9^5•3¹⁴)^5:3^30+(4-1)^102:3¹²]:(2+1)^90 =

= [3^90+(9^5•3¹⁴)^5:3^30+3^102:3¹²]:3^90 =

= [3^90+(9^5•3¹⁴)^5:3^30+3^90]:3^90 =

= [2•3^90+(3^10•3¹⁴)^5:3^30]:3^90 =

= [2•3^90+(3²⁴)^5:3^30]:3^90 =

= [2•3^90+(3^120:3^30)]:3^90 =

= (2•3^90+3^90):3^90 =

= 3•3^90:3^90 =

= 3^91:3^90 =

= 3^(91-90) =
