Question #5 [5 marks): Write a short ARM assembly program that evaluates the following expression. You should not destroy the value of any register other than ro which will get the computed expression value (and of course r15, which is the PC). (Note: All numbers are in decimal.) ro : - 700 [ 16* (r1 r2) - 50 + r3/32 r4] Question #2_[2 marks]: Write a single ARM assembly instruction which will multiply an integer stored in rl by 15 and store the product in r4. (Note: you cannot use any of the explicit multiplication instructions; MLA, MUL, UMLAL, UMULL, SMLAL, or SMULL)
