How to calculate log base 2 of 258
1
First, identify the target value x = 258.
2
Apply the change-of-base formula:
log₂(x) = ln(x) / ln(2).3
Calculate the natural logarithms:
ln(258) ≈ 5.552960
ln(2) ≈ 0.693147
ln(258) ≈ 5.552960
ln(2) ≈ 0.693147
4
Divide the values to get the final result: 8.0112272554.
