Math Problem Statement

log3 (120)

Solution

To compute log3(120)\log_3(120), we can use the change of base formula for logarithms:

logb(x)=log(x)log(b)\log_b(x) = \frac{\log(x)}{\log(b)}

Where log\log is the common logarithm (base 10) or natural logarithm (base ee).

Using this formula, we can rewrite log3(120)\log_3(120) as:

log3(120)=log(120)log(3)\log_3(120) = \frac{\log(120)}{\log(3)}

Now, calculating each value:

  • log(120)2.07918\log(120) \approx 2.07918
  • log(3)0.47712\log(3) \approx 0.47712

Thus:

log3(120)=2.079180.477124.36\log_3(120) = \frac{2.07918}{0.47712} \approx 4.36

So, log3(120)4.36\log_3(120) \approx 4.36.
