Pembahasan:

1.))
1296/1250 = 2^a × 3^b / 5^c
16 × 81 / 2 × 625 = 2^a × 3^b / 5^c
2³ × 3⁴ / 5⁴ = 2^a × 3^b / 5^c
a = 3
b = 4
c = 4

Jadi :
a + b + c
= 3 + 4 + 4
= 7 + 4
= 11 →→ Opsi C

2.))
a^b^c = 9
3^4^1/2 = 9
√3⁴ = 9
√81 = 9
9 = 9
a = 3
b = 4
c = 1/2

Jadi :
√b^a^c
= √(4)^3^1/2
= √4³
= √64
= 8 →→ Opsi B

3.))
8 × 64 × 512 × 1024 = 2^m
2³ × 2^6 × 2^9 × 2^10 = 2^m
2^3+6+9+10 = 2^m
2^9+19 = 2^m
2^28 = 2^m
m = 28

Jadi :
m² - 14² = 28² - 14²
m² - 14² = 784 - 196
m² - 14² = 588 →→ Opsi B

4.))
3^4n+6 × 3^2n-2 / 3^4n+2 : 3n
= 3^4n+6+2n-2 / 3^4+2-n
= 3^6n+4 / 3^3n+2
= 3^6n+4 × 3^-3n-2
= 3^6n+4-3n-2
= 3^6n-3n+4-2
= 3^3n+2 →→ Opsi C
