a$.$ The binary equivalent for the decimal number $50$ is $00110010$

The SHR $($shift right$)$ instruction performs a logical right shift on the destination operand. The highest bit position is filled with a zero. So that shr $2$ means it shifts $2$ bits logically to the right. Shifting right $\backslash ($ n $\backslash )$ bits divides the operand by $\backslash (2^\{$n$\}\backslash ).$

i$.)$ Before shr $2$ the register is:

After shr $2$ the register is:

ii$.)$ The decimal equivalent after shr $2$ is $\backslash ((00001100)\_\{2\}=(12)\_\{10\}\backslash )$

b$.$ The binary equivalent for the decimal number $50$ is $00110010$

The SHL $($shift left$)$ instruction performs a logical left shift on the destination operand, filling the lowest bit with $0$ so that shl $2$ means it shifts $2$ bits logically to the left. Shifting left $\backslash ($ n $\backslash )$ bits multiplies the operand by $2.$

i$.)$ Before shl $2$ the register is:

After shl $2$ the register is:

ii$.)$ The decimal equivalent after shl $2$ is $(11001000)\backslash (2=(200)10\backslash )$

Hope it's clear!!!!!
