Questions & Step-by-Step Solutions

In a certain number system, the number 'A' represents 10. What is the value of 'B' if 'AB' represents 11?
  • Step 1: Understand that 'A' represents the number 10 in this number system.
  • Step 2: Recognize that 'AB' means A multiplied by the base plus B.
  • Step 3: Write the equation for 'AB': A * base + B = 11.
  • Step 4: Substitute the value of A into the equation: 10 * base + B = 11.
  • Step 5: Rearrange the equation to find B: B = 11 - 10 * base.
  • Step 6: Since we need to find B, we need to determine the base. The base must be 1 for B to equal 1.
  • Step 7: Substitute base = 1 into the equation: B = 11 - 10 * 1.
  • Step 8: Calculate B: B = 11 - 10 = 1.
