Penjelasan dengan langkah-langkah:
ASOSIASI KABATAKU
4² + 2² = a(a + 1)
(2²)² + 2² = a(a + 1)
2² × 2² + 2² × 1 = a(a + 1)
2²(2² + 1) = a(a + 1)
→ a = 2² ←
4² + 2² = a(a+1)
16 + 4 = a(a+1)
20 = a(a+1)
16 = 2² + 2²
a = 2²
a = (2²)² + 2² × 1 = a(a+1)
a = (2²)² + 4 × 1 = a(a+1)
a(a+1) = 20
a= 2²
a= 4
kesimpulan :
a(a+1) = 2²(2² +1 )
atau 4(4+1)
