Question 21 of 480
What is the answer when 2434\(_6\) is divided by 42\(_6\)?
- A. 236
- B. 356
- C. 526
- D. 556
Correct Answer:
B
Explanation
To solve the problem of dividing \(2434_6\) by \(42_6\), we first need to convert both numbers from base 6 to base 10 (decimal), perform the division in base 10, and then convert the result back to base 6.
### Step 1: Convert \(2434_6\) to Decimal
To convert a number from base 6 to decimal, we multiply each digit by \(6\) raised to the power of its position (counting from right to left, starting at 0).
For \(2434_6\):
- The rightmost digit (4) is in the \(6^0\) place.
- The next digit (3) is in the \(6^1\) place.
- The next digit (4) is in the \(6^2\) place.
- The leftmost digit (2) is in the \(6^3\) place.
Calculating each term:
- \(2 \times 6^3 = 2 \times 216 = 432\)
- \(4 \times 6^2 = 4 \times 36 = 144\)
- \(3 \times 6^1 = 3 \times 6 = 18\)
- \(4 \times 6^0 = 4 \times 1 = 4\)
Now, we sum these values:
\[
432 + 144 + 18 + 4 = 598
\]
So, \(2434_6 = 598_{10}\).
### Step 2: Convert \(42_6\) to Decimal
Now, we convert \(42_6\) to decimal using the same method:
- The rightmost digit (2) is in the \(6^0\) place.
- The leftmost digit (4) is in the \(6^1\) place.
Calculating each term:
- \(4 \times 6^1 = 4 \times 6 = 24\)
- \(2 \times 6^0 = 2 \times 1 = 2\)
Now, we sum these values:
\[
24 + 2 = 26
\]
So, \(42_6 = 26_{10}\).
### Step 3: Perform the Division in Decimal
Now we divide the two decimal numbers:
\[
598 \div 26
\]
Calculating this gives:
\[
598 \div 26 = 23
\]
This means that \(2434_6\) divided by \(42_6\) equals \(23\) in decimal.
### Step 4: Convert the Result Back to Base 6
Next, we need to convert \(23_{10}\) back to base 6. We do this by repeatedly dividing by 6 and keeping track of the remainders.
1. \(23 \div 6 = 3\) remainder \(5\)
2. \(3 \div 6 = 0\) remainder \(3\)
Reading the remainders from bottom to top, we find that \(23_{10} = 35_6\).
### Step 5: Check the Options
Now, we need to check the options provided:
- A. 236
- B. 356
- C. 526
- D. 556
The correct answer, \(35_6\), is not listed among the options. However, if we consider the possibility of a typographical error in the options, we can see that option B, \(356\), is the closest match to our result \(35_6\) when considering the base representation.
### Conclusion
The correct answer to the division of \(2434_6\) by \(42_6\) is \(35_6\), which corresponds to option B, \(356\), if we assume a typographical error.
### Summary
- Convert numbers from base 6 to decimal for easier calculations.
- Perform the division in decimal.
- Convert the result back to base 6.
- Check the options carefully for potential typographical errors.
This thorough approach ensures that you understand each step of the process and can apply it to similar problems in the future.
