Convert 101 base 3 to 8

1 answer

To convert the number \(101_3\) (base 3) to base 8, we first need to convert it to base 10 (decimal), and then from base 10 to base 8.

Step 1: Convert from base 3 to base 10

The base 3 number \(101_3\) can be converted to decimal using the formula:

\[ (1 \times 3^2) + (0 \times 3^1) + (1 \times 3^0) \]

Calculating it step by step:

\[ 1 \times 3^2 = 1 \times 9 = 9 \] \[ 0 \times 3^1 = 0 \times 3 = 0 \] \[ 1 \times 3^0 = 1 \times 1 = 1 \]

Now, add these results together:

\[ 9 + 0 + 1 = 10 \]

So, \(101_3 = 10_{10}\) in decimal.

Step 2: Convert from base 10 to base 8

Now, we convert \(10_{10}\) to base 8 by division by 8 and keeping track of remainders:

  1. \(10 \div 8 = 1\) remainder \(2\)
  2. \(1 \div 8 = 0\) remainder \(1\)

We stop since the quotient is now zero. Reading the remainders from bottom to top gives us \(12\).

Thus, \(10_{10} = 12_8\) in base 8.

Final Result

The final conversion of \(101_3\) to base 8 is:

\[ 101_3 = 12_8 \]
