Question

1. ^a log2x + (^a logx - ^a logy)= ?
2. A log akar a + log akar b - 1/2 log ab = ?
Mohon bantuannya

Answer 1

1. ᵃlog 2x + (ᵃlog x - ᵃlog y)=
= ᵃlog (2x)(x/y)
= ᵃlog (2x² / y)

2. log√a + log √b - ¹/₂ log ab =
= log a¹/² + log b¹/² - log (ab)¹/²
= log a¹/² + log (b¹/²)/(a¹/².b¹/²)
= log a¹/² + log (1/a¹/²)
= log (a¹/²)(1/a¹/²) 
= log 1
= 0
