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.

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.

Nilai dari ²log4 + ²log12 - ²log6 = ...

- 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.

Harga dari ^alog b . ^b log c . ^c log d ialah …
- ^a log d
- ^dlog a
- Log a - log d
- Log d - log a
- 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.
