The number 67 220 90 4 is written in decimal (base-10) format. Let's break it down:
Step 1: Identify the number of digits
- The number has 7 digits.
- The digits are: 6, 7, 2, 2, 0, 9, 0, 4
Step 2: Interpret the number
- It is not a standard number in any specific base (e.g., binary, hexadecimal).
- It is a decimal number (base-10) with the digits as listed.
Step 3: Convert to decimal (base-10)
To convert the number 67220904 to decimal (base-10), we can use the formula:
$$ \text{Decimal value} = d_7 \times 10^6 + d_6 \times 10^5 + d_5 \times 10^4 + d_4 \times 10^3 + d_3 \times 10^2 + d_2 \times 10^1 + d_1 \times 10^0 $$
Where $ d_7 = 6, d_6 = 7, d_5 = 2, d_4 = 2, d_3 = 0, d_2 = 9, d_1 = 0, d_0 = 4 $
$$ = 6 \times 10^6 + 7 \times 10^5 + 2 \times 10^4 + 2 \times 10^3 + 0 \times 10^2 + 9 \times 10^1 + 0 \times 10^0 + 4 $$
$$ = 6,000,000 + 700,000 + 20,000 + 2,000 + 0 + 90 + 0 + 4 $$
$$ = 6,722,090 + 4 = 6,722,094 $$
✅ Final Answer:
$$ \boxed{6722094} $$
