Question

5^7:(5^3)^2+{16×4^23:(8^3)^5+20^6:10^6×[19-9×(5^7)^3:(5^3)^7]}:112

Answer 1

5⁷ : ( 5³ )² + { 16 x 4²³ : ( 8³ ) ⁵ + 20⁶ : 10⁶ x [ 19 - 9 x ( 5⁷ )³ : ( 5³ )⁷ ] } : 112 = 11

= 5⁷ : 5⁶ + { 2⁴ x 2²ˣ²³ : 2³ ˣ ¹⁵  + ( 20 : 10 )⁶ x [ 19 - 9 x 5⁷ˣ³ : 5³ˣ⁷ ] } : 112 =

= 5 + [ 2 ⁽ ⁴ ⁺ ⁴⁶ ⁻ ⁴⁵ ⁾  + 2⁶ x ( 19 - 9 x 5²¹ : 5²¹ ) ] : 112 =

= 5 + [ 2⁵ + 2⁶ x ( 19 - 9 ) ] : 112 =

= 5 + ( 32 + 64 x 10 ) : 112 =

= 5 + 672 : 112 =

= 5 + 6 =

= 11
