Rewrite each equation as requested. (a) Rewrite as a logarithmic equation. \[ 4^{0}=1 \]

Step 1 ：Rewrite the given equation in logarithmic form: \(4^{0} = 1\)

Step 2 ：Rewrite 4 as \(2^2\): \((2^2)^{0} = 1\)

Step 3 ：Simplify the exponent: \(2^{0} = 1\)

Step 4 ：Write the equation in logarithmic form: \(\log_2 1 = 0\)

Step 5 ：\(\boxed{\log_2 1 = 0}\)
