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:
-31
Step-by-step explanation:
-34 - -17 is actually -34 + 17, so you get -17. -17 - 14 = -31
14 is .608, roundedto the nearest percent 14 is 61% of 23
