(pq/2r)^3÷2p/r^2+1/2q(pq/2r)^3÷2p/r^2+1/2q(pq/2r)^3÷2p/r^2+1/2q原式=p^3*q^3/2*3r*3*r^2/2p+1/2q=p^2q^3/

(pq/2r)^3÷2p/r^2+1/2q
(pq/2r)^3÷2p/r^2+1/2q

(pq/2r)^3÷2p/r^2+1/2q
原式=p^3*q^3/2*3r*3 *r^2/2p+1/2q=p^2q^3/16r+1/2q=p^2q^4/16rq+8r/16rq=8r+p^2q^4/16rp

(p^3q^3/8r)*r^2/2p+1/2q=p^2q^3/8r+1/2q实在没有什么过程可写 看看吧

原式=p^3*q^3/(8r^3)*r^2/2p+1/2q=p^2*q^3/8r+1/2q=(p^2*q^4+4r)/8rq
