log₂(128)
To find the value of log₂(128), we need to determine the power to which we need to raise 2 to get 128
To find the value of log₂(128), we need to determine the power to which we need to raise 2 to get 128.
We start by asking ourselves, “What power of 2 equals 128?”
2^7 = 128
Therefore, we can express log₂(128) as log₂(2^7).
According to logarithm rules, we can rewrite this expression as:
log₂(2^7) = 7 * log₂(2)
The logarithm base 2 of 2 is simply 1, so we can simplify further:
7 * log₂(2) = 7 * 1 = 7
Hence, log₂(128) is equal to 7.
