The equivalent hexadecimal notation for octal number 2550276 is

To convert the octal number 2550276 to hexadecimal, first transform it into binary. Each octal digit corresponds to exactly three binary bits: 2 becomes 010, 5 becomes 101, and so on. Writing this out gives the binary sequence: 010101101000010111110. Next, group these binary bits into sets of four starting from the right to convert directly to hexadecimal: 0101, 0110, 1000, 0101, 1111, 110. Pad the leftmost group with a zero to make it four bits: 0010, 1011, 0100, 0010, 1111, 1110. Converting each group yields the hexadecimal digits: 2, B, 4, 2, F, E. Wait, let's re-evaluate the grouping carefully. \\[2550276_8 = (010)(101)(101)(000)(010)(111)(110)_2 \\ Grouping by 4 from right: 0101 (5), 0110 (6), 1000 (8), 0101 (5), 1111 (F), 110 (6). This seems incorrect based on the options. Let's re-calculate strictly. \\[2_8 = 010, 5_8=101, 5_8=101, 0_8=000, 2_8=010, 7_8=111, 6_8=116 \\ Binary: 010101101000010111110. Grouping from right: 0110 (6), 1110 (E), 0010 (2), 1010 (A), 0101 (5). This is getting messy. Let's try direct conversion via decimal or re-grouping. \\[2550276_8 = 2\
