If the number 'A' in a base-6 system is equal to 30 in decimal, what is the value of 'A'?
Steps
Concepts
Step 1: Understand that 'A' is a number in base-6. This means it uses digits from 0 to 5.
Step 2: The number 'A' is given as '30' in base-6.
Step 3: Break down the base-6 number '30'. The first digit '3' is in the 6^1 place, and the second digit '0' is in the 6^0 place.
Step 4: Calculate the value of 'A' in decimal: Multiply the first digit by 6 raised to the power of its position: 3 * 6^1 = 3 * 6 = 18.
Step 5: Multiply the second digit by 6 raised to the power of its position: 0 * 6^0 = 0 * 1 = 0.
Step 6: Add the two results together: 18 + 0 = 18.
Step 7: Therefore, the value of 'A' in decimal is 18.
