Answer:
2
Step-by-step explanation:
log4/log2 = log(base2)4
NOW, use the definition of logs to find that 2² = 4 so the whole expression equals 2.
(You can do this easily on the calculator also and still get 2 for an answer.)
that's it!
4 = 2x2
log4 = log2x2 = log2 + log2 = 2log2
divide by log2 ans = 2
log4 = log2² = 2log2
Cancel log2 to get the answer: 2
Change of Base Rule:
log base a (x) = (log base b (x)) / (log base b (a))
so...
(log4) / (log2) = log base2(4) = 2
Hopefully this helps--good luck.
log4 = log(2^2) = 2log2 where ^ represents power
=> (log4)/(log2) = 2log2/log2 =2
4=2^2 so log(4)=2log(2)
rewrite as 2log(2)/log(2)=2
