Question

bantu dong plss makasii yaa​

Answer 1

a.

³log 6 + ³log x = 1

³log 6x = 1

3¹ = 6x

x = 3/6

x = 1/2

b.

²log x³ - ²log 27 = 3

²log (x³/27) = 3

2³ = x³/27

x³ = 8 × 27

x³ = 216

x = 6

c.

⁵log 4x³ - ⁵log x = 2

⁵log (4x³/x) = 2

5² = 4x³/x

25 = 4x²

x² = 25/4

x = 5/2 atau 2 1/2 atau 2,5

d.

⁶log 8x + ⁶log x² = 3

⁶log 8x³ = 3

6³ = 8x³

x³ = 216/8

x³ = 27

x = 3
