Correct Answer

A. 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.

Diketahui log 2 = 0,301 dan log 5 = 0,699. Nilai log(4/5) = …
- 0,770
- 0,903
- 0,770 – 1
- 0,903 – 1
- 1
Correct Answer

A. 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.

Jika log 2 = 0,301 dan log 3 = 0,477, maka adalah …
- 0.714
- 0.734
- 0.756
- 0.778
- 0.784
Correct Answer

A. 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.

Nilai dari ²log4 + ²log12 - ²log6 = ...
- 8
- 6
- 5
- 4
- 3
Correct Answer

A. 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.
