How to calculate log base 2 of 23
1
First, identify the target value x = 23.
2
Apply the change-of-base formula:
log₂(x) = ln(x) / ln(2).3
Calculate the natural logarithms:
ln(23) ≈ 3.135494
ln(2) ≈ 0.693147
ln(23) ≈ 3.135494
ln(2) ≈ 0.693147
4
Divide the values to get the final result: 4.5235619561.
