Heyy!
So, iloveonedirection's response would have been correct if there weren't parenthesis around the log equation, its a mistake that literally happens to everyone, I know from experience lol.
Ok so first, lets simplify (log3 1/27):
log(base) of answer= exponent, so we can determine that the base is 3, the answer is 1/27 and the exponent is what we want. so:
3^x = 1/27 , so x= -3 when you solve.
this allows you to substitute -3 for (log3 1/27)
now that leaves you with:
4 (-3) = x
-12 =x
to check your work, just use the calculator:
[log (1/27) /log 3] * 4
which = -12
Hope you understand what I'm trying to say. ;)
Tip: always plug in to a calculator if you aren't sure, have extra time on a test, or anything else lol
Good luck love! you got this :) xx
