Logarithmic scales are used when the range of possible values is very wide, such as the intensity of an earthquake or the acidity of a liquid, in order to avoid the use of large numbers.

\(f(x) = \log_{2}(x) - \log_{2^2}(x)\) \(+ \log_{2^3}(x) - \log_{2^4}(x) \dots\) \(+ \log_{2^{99}}(x) - \log_{2^{100}}(x)\)

What is the value of \(f(2^{(2^{100})}) - (2)f(2^{(2^{99})})\) \(+ (2^2)f(2^{(2^{98})}) - (2^3)f(2^{(2^{97})}) \dots\) \(+ (2^{98})f(2^{(2^{2})}) - (2^{99})f(2^{(2^{1})})\) ?
