Question

[2²⋅3+(11²−7⁰):2³]⁷:9¹⁰​

Answer 1

$\it =[4\cdot3+(121-1):8]^7:9^{10}=(12+15)^7:9^{10}=27^7:9^{10}=\\ \\ =(3^3)^7:(3^2)^{10}=3^{21}:3^{20}=3^{21-20}=3^1=3$

Answer 2

[4•3+(121-1):2^3]^7:9^10
(4•3+120:8)^7:(3^2)^10
(12+15)^7:3^2•10
27^7:3^20
(3^3)^7:3^20
3^3•7:3^20
3^21:3^20
3^21-20
3^1=3
