Tolong dibantu ya no 10-14

2 log a + 2 log b = 12
bdsrkn sifat log :
→ 2 log (a.b) = 12 >>> 2^12 = ab....[pers 1]

3 *2 log a - 2 log b = 4
→ 2 log a^3 - 2 log b = 4
→ 2 log (a^3)/b = 4 >>> 2^4 = a^3 / b...[pers 2]

dari [pers 2]
2^4 = a^3 / b
b = a^3 / 2^4 ....[pers 3]

subt.nilai b ke [pers 1]
2^12 = ab
2^12 = a. (a^3 / 2^4)
2^12 . 2^4 = a^4
2^16 = a^4
4√2^16 = 4√a^4
2^4 = a ※→→ dpt nilai a

subt.nilai a ke [pers 1] atau boleh jg pers 2
2^12 = ab
2^12 = 2^4 . b
2^12 / 2^4 = b
2^8 = b ※→→ dpt nilai b

↓
a + b = 2^4 + 2^8
= 16 + 256 = 272
