Is x/m(m^2+n^2+k^2)=xm+yn+zk?
1.z/k=x/m
2.x/m=y/n
Need this explained in steps. Want to break this down and simplify or rephrase somehow. Please do not just give answer or agreement that you agree with previous answer. Whats most beneficial for eveyone is different explanations.
Trying to figure out the most efficient way to tackle this.

ANS C
(x/m)(m^2+n^2+k^2) - break this into 3 terms
First xm
Second x*n^2/m
Third x*k^2/m
Stmt 1 - z/k=x/m -- We can solve third term as k^2*z/k = zk
can't do anything about second term so NOT SUFF
Stmt 2 x/m=y/n -- We can solve second term as yn but can't do much about third term so NOT SUFF
Together, we find the answer as xm+yn+zk SUFF
Hope this clarifies your doubt
