How to calculate log base 2 of 47
1
First, identify the target value x = 47.
2
Apply the change-of-base formula:
log₂(x) = ln(x) / ln(2).3
Calculate the natural logarithms:
ln(47) ≈ 3.850148
ln(2) ≈ 0.693147
ln(47) ≈ 3.850148
ln(2) ≈ 0.693147
4
Divide the values to get the final result: 5.5545888517.
