bantu dong plss makasii yaa
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
