Boolean Function - Help needed quickly

Hi,

Can anyone help provide solution for this ASAP. I don't have much idea how to solve it.

Request to solve both the questions with little bit of explanation if possible so that i can understand the concept in a better way.

Q: Simplify the following Boolean function F together with don't care conditions d, then express the simplified function in sum of minterms.

$F(x,y,z) = \Sigma{(0,1,2,4,5)}$
$d(x,y,z) = \Sigma{(3,6,7)}$

$F(A,B,C,D) = \Sigma(0,6,8,13,14)$
$d(A,B,C,D) = \Sigma(2,4,10)$

Thanks in ADVANCE,

Best Regards,
