Write each binary number first as an octal number and then as a hexadecimal number. 

1111010001_2

### Converting Binary to Octal and Hexadecimal

**Problem Statement:**
Write each binary number first as an octal number and then as a hexadecimal number.

Binary Number: 1111010001<sub>2</sub>

**Solution:**

**Step 1: Convert Binary to Octal**
- Group the binary digits into sets of three, starting from the right. Add extra zeros at the start if the leftmost group has fewer than three digits.
  
  001 111 010 001
  
- Convert each group of three binary digits to its octal equivalent:
  - 001<sub>2</sub> = 1<sub>8</sub>
  - 111<sub>2</sub> = 7<sub>8</sub>
  - 010<sub>2</sub> = 2<sub>8</sub>
  - 001<sub>2</sub> = 1<sub>8</sub>
  
- Combine the octal digits to form the final octal number:
  1721<sub>8</sub>

**Step 2: Convert Binary to Hexadecimal**
- Group the binary digits into sets of four, starting from the right. Add extra zeros at the start if the leftmost group has fewer than four digits.
  
  0011 1101 0001
  
- Convert each group of four binary digits to its hexadecimal equivalent:
  - 0011<sub>2</sub> = 3<sub>16</sub>
  - 1101<sub>2</sub> = D<sub>16</sub>
  - 0001<sub>2</sub> = 1<sub>16</sub>
  
- Combine the hexadecimal digits to form the final hexadecimal number:
  3D1<sub>16</sub>

**Summary:**
- The octal representation of 1111010001<sub>2</sub> is 1721<sub>8</sub>.
- The hexadecimal representation of 1111010001<sub>2</sub> is 3D1<sub>16</sub>.
