Identify the given logarithmic expression: \(\log_2\left(x+1\right)^2\).
Recall the power property of logarithms, which states that \(\log_b\left(a^n\right) = n \cdot \log_b(a)\), where \(b\) is the base, \(a\) is the argument, and \(n\) is the exponent.
Apply the power property by bringing the exponent 2 in front of the logarithm: \(\log_2\left(x+1\right)^2 = 2 \cdot \log_2\left(x+1\right)\).
Rewrite the expression clearly as \(2\log_2\left(x+1\right)\).
This is the simplified form using the power property of logarithms.
