if log_2 3=a and log_3 7=b, what is log_2 14?
the answer is 1 + ab

log_2 14 = log_2 2 + log_2 7
=1 + log_3 7/log_3 2
=1 + b/log_3 2
=1 + b/[log_2 2/log_2 3]
=1 + b[log_2 3/log_2 2]
=1 + ab

the answer is 1 + ab

log_2 14 = log_2 2 + log_2 7
=1 + log_3 7/log_3 2
=1 + b/log_3 2
=1 + b/[log_2 2/log_2 3]
=1 + b[log_2 3/log_2 2]
=1 + ab

bet you ace math test
