The value of logy will be 7.457.
The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.
In another word, a logarithm is a different way to denote any number.
Given that log x is twice log y
So,
logx = 2 logy
logx = logy² ( by property of log)
x = y²
Now given that x = 3 × 10⁶
So,
y² = 3 × 10⁶
y = 1732.5
Now,
Logy will be
log1732.5 = 7.457
Hence "The value of logy will be 7.457".
