Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
Subtract 13 from both sides
-5x = -17 - 13
Simplify -17 - 13 to -30
-5x = -30
Divide both sides by -5
x = -30/-5
Two negatives make a positive
x = 30/5
Simplify 30/5 to 6
<u>x = 6</u>
