3³ + 3¹⁰ : 3⁸ • 3 + 3 • 3⁷ : 3⁵ + 2 • 3¹⁰ : ( 5 • 3⁵ + 3⁵ ) + 9 • 3³ =
= 3³ + 3³ + 3 • 3⁷ : 3⁵ + 2 • 3¹⁰ : ( 5 • 3⁵ + 3⁵ ) + 9 • 3³ =
= 3³ + 3³ + 3³ + 2 • 3¹⁰ : ( 5 • 3⁵ + 3⁵ ) + 9 • 3³ =
= 3³ + 3³ + 3³ + 2 • 3¹⁰ : ( 6 • 3⁵ ) + 9 • 3³ =
= 3³ + 3³ + 3³ + 2 • 3¹⁰ supra 6 • 3⁵ + 9 • 3³ =
= 12 • 3³ + 2 • 3¹⁰ supra 6 • 3⁵ =
= 12 • 3³ + 2 • 3⁵ supra 6 =
= 12 • 3³ + 3⁵ supra 3 =
= 12 • 3 ³ + 3⁴ =
= 4 • 3 • 3³ + 3⁴ =
= 4 • 3⁴ + 3⁴ =
= ( 4 + 1 ) • 3⁴ =
= 5 • 3⁴ =
= 5 • 81 =
= 405
