Squares (1² to 50²) Key: 25²=625, 35²=1225, 45²=2025

Cubes (1³ to 30³) Key: 5³=125, 6³=216, 25³=15625

Powers & Golden Equivalences

Powers of 2 (Up to 2¹²) & Key Identities

2¹ = 2, 2² = 4, 2³ = 8, 2⁴ = 16

2⁵ = 32, 2⁶ = 64, 2⁷ = 128, 2⁸ = 256

2⁹ = 512, 2¹⁰ = 1024, 2¹¹ = 2048, 2¹² = 4096

Key Identity Rule:
2⁶ = 4³ = 8² = 64
2¹² = 4⁶ = 16³ = 64² = 4096
