The value of the DS register is 2016H. And the BX register contains a 16 bit value which is equal to 2016H. 0008H is added to BX.ADD BX, 0008H.The register AX contains some value which needs to be stored at a location as follows: MOV [BX], AX. Calculate the address at which the value of the AX will be stored.
