Question 404759: Hello,
Could someone please help with these two problems, I am done with my assignment but can't figure these two out:
3. Give a counterexample to the claim log(st)=(log s)(log t)
4. Give a counter example to the claim log(5x)= 5 log x

3. Give a counterexample to the claim log(st)=(log s)(log t)
s = 4, t = 5
log(st) = log(20) =~ 1.30103
log(4)*log(5) =~ 0.42082
---------------------
4. Give a counter example to the claim log(5x)= 5 log x
x = 10
log(50) =~ 1.69897
5*log(10) = 5
