Answer

Create your assembly language source file. The Ex__8_expr_arm64.s file contains the following example solution to this exercise:

.text
.global _start
_start:
    // Print the leading output string
    ldr     x1, =msg1
    mov     x2, #msg1_len
    bl      print_string
    // Compute [(129 – 66) * (445 + 136)] / 3
    mov     x0, #129
    sub     x0, x0, #66
    mov     x1, #445
    add     x1, x1, #136
    mul     x0, x1, x0
    mov     x1, #3
    udiv    x0, x0, x1
    // Print the upper byte of the result
    mov     x19, x0
    lsr     x0, x0, #8
    bl      print_byte
    // Print the lower byte of the result    
    mov     x0, x19
    bl      print_byte
    
    // Print the trailng output string
    ldr     x1, =msg2
    mov     x2, #msg2_len
    bl      print_string
    
    // Exit the program with syscall 93, returning status 0
    mov     x0, #0
    mov     x8, #93
    svc     0
// Print a string; x1=string address, x2=string length
print_string:
    mov...
