The correct answer is the last choice. You use the quadratic formula
-b+-√(b^2-4ac)/2a
-3+-√(9-4*1*7)/2
-3+-√-19/2
=-3+-√19/2
Hope this helps!
Answer:
1.3917
Step-by-step explanation:
logb 15 =
We know that log (ac) = log a + log c
logb 15 = logb (3*5)
= logb (3) + log b (5)
logb(3) = 0.5646 and logb(5) = 0.8271
= 0.5646 + 0.8271
1.3917
