Final answer:
The expression 2⁷ = 128 can be rewritten in logarithmic form as log₂ 128 = 7.
Step-by-step explanation:
The expression 2⁷ = 128 can be rewritten in logarithmic form as log₂ 128 = 7.
The logarithm of a number to a certain base is the exponent to which the base must be raised to obtain that number. In this case, the base is 2 and the number is 128, so we write log₂ 128 = 7.
This means that 2 raised to the power of 7 is equal to 128.
