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
Answer:
3
Step-by-step explanation:
A factor is 3 because 54xy / 3 = 18xy, 45x / 3 = 15x, 18y / 3 = 6y, and 15 / 3 = 5
Add 6 to both sides so you have -2x = 18. If you divide both sides by -2 you will get x = -9
Answer:
I could be wrong but I think its the third one
