Given: U = {j, k, l, m,n, p}?
R= {k,m,p}
S= {j,l,n,p}
T= {l,m,n}

Find:

S ? T

R ? T '

S ' ? ( T ' ? R ')

Do you know what the symbols mean?

Given: U = {j, k, l, m, n, p}

R= {k, m, p}, R' = {j, l, n}
S= {j, l, n, p}, S' = {k, m}
T= {l, m, n}, T' = {j, k, p}


How about this??

S ' ? ( T ' ? R ') = {k, m} ? ({j, k, p} ? {j, l, n})
= {k, m} ? {j, k, l, n, p} = {k}

That's the spirit. It looks good. Why do you doubt?
