The unnamed math x that corresponds to the text "blackers" is [1, 9, 4].
The unnamed math x that corresponds to the text "blackers" is:
[1, 9, 4]
To find this, we can use the following steps:
1. Break the text "blackers" into its individual characters: `b`, `l`, `a`, `c`, `k`, `e`, `r`, and `s`.
2. Find the corresponding numbers in the encoding matrix, D:
[1, 2, 5]
[0, -4, 1]
[0, 3, -1]
3. Multiply each number in D by its corresponding character in the text, and add the results together. For example, to find the first element of the resulting matrix, we would multiply the first element of D (1) by the first character in the text (`b`):
1 * b = 1
We would then do the same for the second element of D and the second character in the text, and so on.
Therefore, the unnamed math x that corresponds to the text "blackers" is [1, 9, 4].
