Hint : Multiplying a matrix M by a diagonal matrix by the right (meaning M x D) multiplies the columns of M by the coefficients of D

#

Try multiplying $M = \begin{pmatrix}1&1&1\1&1&1\1&1&1\end{pmatrix}$ by $D = \begin{pmatrix}3&0&0\0&5&0\0&0&7\end{pmatrix}$

Ohh i can't solf it

Did you try the computation I suggested?

#

If you have any questions on how to do matrix product, feel free to @ me

Okay i have tried

#

How about it

That's right! See how every column of B gets multiplied by the diagonal terms of D ?

#

Now, do you see what is the answer to your original question?

#

Btw that's a detail but, instead of saying "the value of [...] will be true" you should say "the value of [...] will be appropriate / suitable"
Because a number cannot be "true" or "false"
