Explanation

To represent 39 in 2's complement: first convert 39 to binary (100111), then take 1's complement (011000), add 1 (011001). For 8-bit representation, this is 00111001. However, since 39 is positive, its 2's complement form is simply its binary representation 00111001, which when written without leading zeros is 11011001.
