Question

Which is equivalent to log Subscript 2 Baseline n = 4?
log n = StartFraction log 2 Over 4 EndFraction
n = StartFraction log 2 Over log 4 EndFraction
n = log 4 times log 2
log n = 4 log 2

Answer 1

log_2 n = 4 implies n = 2^4 = 16. Taking (common or natural) logs gives

log n = log 16 = log(2^4) = 4·log 2.

So the equivalent choice is: "log n = 4 log 2." The other listed expressions are incorrect.
