1. The problem statement, all variables and given/known data

Solve this equation without using the Karnaugh table

2. Relevant equations

a'b'cd'+a'b'cd+a'bc'd+a'bcd+ab'cd+abc'd

3. The attempt at a solution

a'b'cd'+a'b'cd+a'bc'd+a'bcd+ab'cd+abc'd=

1+a'b'cd+a'bc'd+a'bcd+ab'cd=

1+b'cd*(a'+a)+a'bc'd+a'bcd=

1+b'cd*1+a'bc'd+a'bcd=

1+b'cd+a'bc'd+a'bcd=

1+b'cd+a'bd*1=

1+b'cd+a'bd
