Use the register and memory values in the table below for this question. Assume a 32-bit machine. Assume each of the following questions starts from the table values; that is, DO NOT use value changes from one question as propagating into future parts of the question.

Register	Value	Memory Location	Value
R1	12	12	16
R2	16	16	20
R3	20	20	24
R4	24	24	28

a)Give the values of R1, R2, and R3 after this instruction: addR1, R2, R3

b)What values will be in R1 and R3 after this instruction is executed: lwR2, 8(R1)

c)Whatvalues will be in R2 and R4after this instruction is executed: addi R2, R4, #16
