Answer:

=      p^2 q^2    +       25 r^2     +      10 pqr

Step-by-step explanation:

Given :   ( pq + 5r )^2​

This  is  in  the  form  of :    ( a + b )^2   =  a^2    +     b^2     +    2 * a* b  

So :    

        =     ( pq )^2     +     ( 5r )^2     +      2 * pq * 5r

        =      p^2 q^2    +       25 r^2     +      10 pqr
