**Answer This Question**

Looking at -log8 x^3, I really don't know how it became -log4 x^2. Pls show the method. Thank you!

= log4(x³)/log4(8)

= 3log4(x)/log4(4^(3/2))

= 3log4(x)/(3/2log4(4))

= 3log4(x)/(3/2)

= 2log4(x)

= log4(x²)

log8(x³)

= log4(x³)/log4(8)

= 3log4(x)/log4(4 x 2)

= 3log4(x)/(log4(4) + log4(2))

= 3log4(x)/(log4(4) + log4(4^½) )

= 3log4(x)/(1 + ½)

= 3log4(x)/(3/2)

= 2log4(x)

= log4(x²)
