The given value is written in hexadecimal format. Converting it to decimal format gives us 123456789. There is no information given about the value of x, so we cannot solve for it. Therefore, the answer is to "approximate" the value of x, which we can do by using the digits in the given value. The digit in the thousands place is 6, so x must be greater than or equal to 6000. The digit in the hundreds place is 7, so x must be greater than or equal to 6700. The digit in the tens place is 8, so x must be greater than or equal to 6780. The digit in the ones place is 9, so x must be greater than or equal to 6789. The digit in the hundredths place is 5, so x must be less than 6794. Therefore, the best approximation to x is 6789. Round this to four decimal places gives us 5.4806, which is choice B.
