Answer 2

Converting 2FA(16) to decimal:

To convert the hexadecimal number 2FA to decimal, we can use the following steps:

1. Write down the hexadecimal number: 2FA. 2. Assign a decimal value to each digit in the hexadecimal number. The rightmost digit has a decimal value of 1, the next digit to the left has a decimal value of 16, and so on. 3. Multiply each digit by its corresponding decimal value. 4. Sum up the results to get the decimal equivalent.

Let's apply these steps to convert 2FA(16) to decimal:

2FA(16) = (2 * 16^2) + (15 * 16^1) + (10 * 16^0) = (2 * 256) + (15 * 16) + (10 * 1) = 512 + 240 + 10 = 762.

Therefore, 2FA(16) is equal to 762 in decimal [[1]](https://www.hse.ru/data/921/036/1226/lec.pdf).

Converting 271(8) to decimal:

To convert the octal number 271 to decimal, we can use the following steps:

1. Write down the octal number: 271. 2. Assign a decimal value to each digit in the octal number. The rightmost digit has a decimal value of 1, the next digit to the left has a decimal value of 8, and so on. 3. Multiply each digit by its corresponding decimal value. 4. Sum up the results to get the decimal equivalent.

Let's apply these steps to convert 271(8) to decimal:

271(8) = (2 * 8^2) + (7 * 8^1) + (1 * 8^0) = (2 * 64) + (7 * 8) + (1 * 1) = 128 + 56 + 1 = 185.

Therefore, 271(8) is equal to 185 in decimal.
