➊ 1⍻b = 0
The power that the base must be raised to in order to yield 1 is the 0th.
➋ b⍻b = 1
The power that the base must be raised to in order to yield the base itself is the 1st.
➌ (b˄x)⍻b = x
The power that the base must be raised to in order to yield the base raised to the power of a number is the power of the number.
➍ b˄(x⍻b) = x
A number raised to the power that the number must be raised to in order to yield x is x.
