log3(13)       

using change of base formula: 

logb(m) = log%28a%2C%28m%29%29%2Flog%28a%2C%28b%29%29

On your TI-84 calculator

1. Press ON
2. Press CLEAR
3. Press LOG       see log(
4. Type 13)        see log(13)
5. Press ÷         see log(13)/
6. Press LOG       see log(13)/log(
7. Type 3)         see log(13)/log(3)
8. Press ENTER     see 2.334717519

Answer: 2.334717519
