Final answer:
The instructions Id x5 and 8(x8) differ from Id 5 and 8(x8). Iw x5 and 8(x8) have a different meaning than Id x5 and Id 5. Finally, the instruction Idu x5 and 8(x8) may involve comparing values.
Step-by-step explanation:
The instructions Id x5 and 8(x8) are different from the instructions Id 5 and 8(x8). 'Id x5' refers to identifying or labeling something as 'x5', while '8(x8)' means multiplying 8 by the value of 'x8'. On the other hand, 'Id 5' means identifying something as '5', and '8(x8)' again refers to multiplying 8 by the value of 'x8'.
The instructions Iw x5 and 8(x8) are also different from 'Id x5' and 'Id 5'. 'Iw x5' is not a commonly used instruction, but it could potentially mean 'In writing, write x5', indicating that the value of 'x5' should be written down. Similarly, '8(x8)' means multiplying 8 by the value of 'x8'.
The instruction Idu x5 and 8(x8) is not a commonly used instruction either. However, if we interpret it as 'Identify whether x5 is less than x8', then it would involve comparing the values of 'x5' and 'x8'. Again, '8(x8)' means multiplying 8 by the value of 'x8'.
