Question 1 (1 point)

Answer 1

Answer:

• 1. a, 2. d, 3. b, 4. d, 5. a, 6. b, 7. d, 8. a, 9. d, 10. b

Step-by-step explanation:

Question 1

• log3 9  = log 3 3² = 2

Question 2

• log8 12 = log 12/log 8 = 1.19  

Question 3  

• ln 7 = log 7 / log e = 1.95

Question 4  

• log4 14 as a logarithm of base 3
• log4 14 = log3 14/ log3 4

Question 5  

• log6 5 as a logarithm of base 4
• log6 5 = log4 5/ log4 6

Question 6

• log4 (y − 9) + log4 3 = log4 81
• log4 (3y - 27) = log4 81
• 3y - 27 = 81
• 3y = 108
• y = 36

Question 7

• 5 log2 k − 8 log2 m + 10 log2 n
• log2 k^5 - log2 m^8 + log2 n^10 =
• log2 (k^5n^10/m^8)

Question 8

• 2 log x = log 36  log x^2 = log 36
• x^2 = 36
• x = √36
• x = ± 6

Question 9  

• 4 log12 2 + log12 x = log12 96  log12 16x = log12 96
• 16x = 96
• x = 6

Question 10

• 2 log2 2 + 2 log2 6 − log2 3x = 3
• log2 (4*36/3x) = 3
• 48/x = 2^3
• 48/x = 8
• x = 48/8
• x = 6
