What is log6^e f rewritten using the power property?
marishachu [46]

Given expression : log_6e^f ..

We need to apply power property of logs to rewrite it.

According to log rule of exponents:

log_b a^n = n log_b(a)

If we compare given expression with the rule the exponent part is f, base is 6.

Therefore, we need to bring exponent f in front of log.

Therefore, log_6e^f  = flog_6 e.

<h3>And correct option is second option flog_6 e.</h3>

Fred can run 12 miles in 1 hour and can bike 30 miles in 2 hours. What percent of Fred’s average biking speed is his average run
S_A_V [24]

first thing you have to do is find the rate for the bike so you divide 30 by 2 and you get 15 after you do that you make a problem to find the percentage so you take x/100 and 12/15 then you take 12 times 100 and that gives you 1200 then you divide by 15 and get 80. So the answer is 80%
