Question 1
LogarithmsEvaluate log√24 + log½16 − log432
- A.−5.5
- B.−2.5
- C.2.5
- D.5.5
Show the answer and explanation
Answer: B (−2.5)
Explanation
log√24 = 4 because (√2)4 = 4; log½16 = −4; log432 = 5/2. So 4 − 4 − 2.5 = −2.5.
Evaluate log√24 + log½16 − log432
Answer: B (−2.5)
log√24 = 4 because (√2)4 = 4; log½16 = −4; log432 = 5/2. So 4 − 4 − 2.5 = −2.5.
