Questions and Answers
  • 1. 

    Diketahui log 2 = 0,301 dan log 5 = 0,699. Nilai log(4/5) = …

    • A.

      0,770

    • B.

      0,903

    • C.

      0,770 – 1

    • D.

      0,903 – 1

    • E.

      1

    Correct Answer
    D. 0,903 – 1
    Explanation
    The given question provides the values of log 2 and log 5, which are 0.301 and 0.699 respectively. The expression log(4/5) can be simplified as log(4) - log(5) using the logarithmic property of division. Substituting the given values, log(4/5) = log(4) - log(5) = 0.903 - 1 = -0.097. Therefore, the correct answer is 0.903 - 1.

  • 3. 

    Jika log 2 = 0,301 dan log 3 = 0,477, maka  adalah …

    • A.

      0.714

    • B.

      0.734

    • C.

      0.756

    • D.

      0.778

    • E.

      0.784

    Correct Answer
    E. 0.784
    Explanation
    The correct answer is 0.784. This can be determined by using the logarithmic properties. We can rewrite the given expression as log 2^3. By using the property log a^b = b * log a, we can simplify this to 3 * log 2. Plugging in the given values for log 2, we get 3 * 0.301 = 0.903. Therefore, the answer is the antilog of 0.903, which is 0.784.

    Correct Answer
    B. 6
    Explanation
    The given sequence is decreasing by 2 each time. Starting from 8, subtracting 2 gives 6, then subtracting 2 again gives 4, and so on. Therefore, the next number in the sequence would be 6.

    Rate this question:

    • E.

      3

    Correct Answer
    E. 3
    Explanation
    The given expression can be simplified using the properties of logarithms. We can rewrite 2log4 + 2log12 - 2log6 as log4^2 + log12^2 - log6^2. Applying the exponent rule of logarithms, this becomes log16 + log144 - log36. Using the addition rule of logarithms, we can combine these logarithms into a single logarithm: log(16*144/36). Simplifying further, we get log(576/36), which is equal to log16. Since log16 is equal to 4, the final value of the expression is 4. Therefore, the correct answer is 4.

    • A.

      a log d

    • B.

      d log a

    • C.

      Log a - log d

    • D.

      Log d - log a

    • E.

      Log a. log d

    Correct Answer
    A. a log d
    Explanation
    The given expression can be simplified using logarithmic properties. We can rewrite the expression as log(a) * log(b) * log(c) * log(d). Since multiplication is commutative, we can rearrange the terms as log(a) * log(d) * log(b) * log(c). By using the property log(a) + log(b) = log(a * b), we can combine log(a) and log(d) to get log(a * d). Therefore, the correct answer is a log d.
