Question 92941: I need help - PLEASE
I need to convert between logarithmic and exponential form:
1. log2 16 = 4 (to exponential)
2. log5 125 = 3 (same)
3. 10^-1 = 0.1 ( to logarithmic)
I need to evaluate these:
log3 81
log4 256
I am lost - please help

1. 2%5E4+=+16
2. 5%5E3+=+125
3. log%2810%2C+0.1%29+=+-1
4. log%283%2C81%29+=+log%283%2C%283%5E4%29%29+=+4%2Alog%283%2C3%29+=+4%2A1+=+4
5. log%284%2C256%29+=+log%284%2C%284%5E4%29%29+=+4%2Alog%284%2C4%29+=+4%2A1+=+4
