logax = 1, logay = 2, logaz = 4 হলে loga{(x3y2)/z} এর মান কত?

A 4

B 2

C 5

D 3

Solution

Correct Answer: Option D

logax = 1,logay=2, logaz=4
⇒x=a1
∴y=a2
∴z=a4
∴loga{(x3.y2)/z} = loga {(a3.a4)/a4
                         =logaa3
                          =3logaa
                           =3.1=3
