Evaluate the log. 27} 81" alt="log\frac{1}{27} 81" align="absmiddle" class="latex-formula">

Answer 1

Answer:

-4/3.

Step-by-step explanation:

Using the change of base formula  convert to  log 3:

logb x = loga x / loga b

log(1/27) 81 = log3 81 / log3 1/27

log3 81  = 4 ( because 3^4 = 81) and log3 1/27 = -3 (because 3^-3 = 1/27)

So  log(1/27) 81 = 4/-3 = -4/3.
