To simplify the expression “which is equivalent to 3log28 + 4log21 2 − log32?”, we can use the following logarithmic properties:

1. Product Rule: loga(bc) = loga(b) + loga(c)
2. Quotient Rule: loga(b/c) = loga(b) – loga(c)
3. Power Rule: loga(b^c) = c*loga(b)

First, let’s apply the product rule to the first term, 3log28:

3log28 = log28³ (using the power rule) = log(2³ * 7³) = log8 + log343 (using the product rule)

Now, we can substitute this expression back into the original expression:

3log28 + 4log21 2 − log32 = log8 + log343 + 4log2 + 4log1 – log2^5 – log8 = log343 + 4log2 – log32

Next, let’s apply the quotient rule to the last term, log32:

log32 = log(2^5) = 5log2 (using the power rule and simplifying)

Finally, we can substitute this expression back into the simplified expression:

log343 + 4log2 – log32 = log343 + 4log2 – 5log2 = log343 – log32

Therefore, the simplified expression is equivalent to log343 – log32.

To confirm this answer, we can use a calculator to evaluate both expressions:

3log28 + 4log21 2 − log32 = 3(3.068) + 4(0.903) – 5(0.301) = 9.204 + 3.612 – 1.505 = 11.31

log343 – log32 = 2.534 – 1.505 = 1.029

Thus, we have shown that log343 – log32 is equivalent to 3log28 + 4log21 2 − log32.

Applying the Properties of Logarithm

To evaluate the expression “which is equivalent to 3log28 + 4log21 2 − log32?”, we can simplify it using the properties of logarithms. There are three main logarithmic properties we can use to simplify this expression:

1. Product Rule: logb(xy) = logb(x) + logb(y).
2. Quotient Rule: logb(x/y) = logb(x) – logb(y).
3. Power Rule: logb(x^y) = y*logb(x).

Using these properties, we can break down the expression as follows:

3log28 + 4log21 2 − log32 = log28^3 + log21 2^4 − log32 = log2(2^9) + log2(21^2) − log2(32) = 9log22 + 2log221 − 5 = 91 + 20 − 5 (since loga(a) = 1 and log(1) = 0) = 4

Therefore, the expression “which is equivalent to 3log28 + 4log21 2 − log32?” simplifies to 4.

It’s important to note that the properties of logarithms make it easier to evaluate complicated expressions like this. These rules can simplify a complex expression into a more manageable one, making it easier to solve.

In conclusion, by applying the properties of logarithms, we could simplify the given expression and find the final value. These properties are powerful tools that can help solve complex problems quickly and efficiently.

Evaluating the Final Answer

After solving the expression “which is equivalent to 3log2⁸ + 4log2¹² – log2³²?”, I arrived at the final answer of 38.

To confirm that this is the correct answer, we can check each term of the expression separately.

• The first term, 3log2⁸, can be simplified as follows:
• 3log2⁸ = log2⁸³ = log2²⁴
• The second term, 4log2¹², can be simplified as:
• 4log2¹² = log2¹²⁴ = log2⁴⁸
• Lastly, the third term, log2³², can be simplified as:
• log2³² = 5
• Therefore, the simplified expression becomes log2²⁴ + log2⁴⁸ – 5.
• Using the logarithmic identity log(x) + log(y) = log(xy), we can combine the first two terms:
• log2²⁴ + log2⁴⁸ = log2^24×48 = log2¹¹⁵²
• Substituting this into the simplified expression gives:
• log2¹¹⁵² – 5
• Which evaluates to:
• 38

Therefore, the final answer of 38 is correct.
