Multiplication of pq+qr+rp and ‘zero’ isa)pq+qr b)pq+rpc)p...
To multiply pq, qr, and rp, we can use the associative property of multiplication. That is, we can multiply two of the numbers first and then multiply the result with the third number.

Let's assume that we will first multiply pq and qr:

(pq)(qr) = p*q*q*r = p*q^2*r

Now we will multiply the result with rp:

(pq)(qr)(rp) = (p*q^2*r)*r*p = p*q^2*r^2*p

Therefore, the multiplication of pq, qr, and rp is p*q^2*r^2*p.
