Salut!

A = 13⁴ : 13³ - 5² • 5⁵ : 5⁶ + 17⁹ : (17²)⁴ + [59 - 6² + 3 • (12⁴ : 2⁷ : 3³ - 4)] • 5 =

= 13 - 5⁷ : 5⁶ + 17⁹ : 17⁸ + [59 - 36 + 3 • ( (2²)⁴ • 3⁴ : 2⁷ : 3³ - 4)] • 5 =

= 13 - 5 + 17 + [ 23 + 3 • (2⁸ : 2⁷ • 3⁴ : 3³ - 4)] • 5 =

= 25 + [ 23 + 3 • (2 • 3 - 4)] • 5 =

= 25 + [ 23 + 3 • (6 - 4)] • 5 =

= 25 + [ 23 + 3 • 2 ] • 5 =

= 25 + [ 23 + 6 ] • 5 =

= 25 + 29 • 5 =

= 25 + 145 =

= 170
