9\(_{10}\) is equivalent to X\(_8\), where X is?        

Answer Details

To convert a number from base 10 to base 8, we need to divide the number by 8 and keep track of the remainder at each step until the quotient becomes 0. Let's start with the number 9 in base 10. If we divide 9 by 8, the quotient is 1 and the remainder is 1. So, we can write 9 in base 8 as 11, where the first digit represents the quotient and the second digit represents the remainder. Therefore, X is 1, and the answer is 11.
