Ditentukan x= ²log 3 dan y= ²log5, maka ²log (9 akar pangakat 3 dari 5)

x= ²log 3 dan y= ²log5

²log(9 . ∛5)
= ²log 9   +   ²log ∛5
= ²log 3²  +  ²log 5^(1/3)
= 2 . ²log 3  +  (1/3) . ²log 5
= 2 . x + (1/3)y
= (6x + y) / 3

[tex] x = ^2log3 \\ y = ^2log5 [/tex]

[tex] ^2log(9.^3\sqrt{5}) [/tex]
[tex] ^2log((3^2).(5^{\frac{1}{3}}) [/tex]
[tex] ^2log(3^2) +^2log(5^{\frac{1}{3}}) [/tex]
[tex] 2.^2log3 + \frac{1}{3}.^2log5 [/tex]
[tex] 2x + \frac{1}{3}y [/tex]
