an example, convert
(
140
)
8
into a decimal number.
Step 1: Write 140 with the power of 8. Start from the right-hand side.
1 × 82 + 4 × 81 + 0 × 80
Step 2: Evaluate the power of 8 values for each octal number.
82 = 64, 81 = 8, 80 = 1
Step 3: Multiply each of the power of 8 numbers with the respective numbers.
1 × 64 + 4 × 8 + 0 × 1 = 64 + 32 + 0
Step 4: Add the values to obtain the decimal number.
64 + 32 + 0 = 96.
Therefore,
( 140 ) 8 = ( 96 ) 10 .
