The value of log₁₂ y² will be : 32
Explanation
log₁₂ y²
According to the property of logarithm, if there is any exponent in the number of log, then we can just take out that exponent part to the front of the log, like: log (a)ᵇ = b × log (a)
Here, the exponent in the number of log is 2. So, according to the above property, we will get: 2 log₁₂ y
Now, the value of log₁₂ y is given as 16. So,
2 log₁₂ y
⇒ 2 (16) = 32
