Let p>3 be a prime, and let m be an integer with p∤m. In the paper we solve some conjectures of Z.W. Sun concerning ∑k=0p−1(2kk)3/mk(modp2), ∑k=0p−1(2kk)(4k2k)/mk(modp) and ∑k=0p−1(2kk)2(4k2k)/mk(modp2). In particular, we show that ∑k=0p−12(2kk)3≡0(modp2) for p≡3,5,6(mod7). Let {Pn(x)} be the Legendre polynomials. In the paper we also show that P[p4](t)≡−(6p)∑x=0p−1(x3−32(3t+5)x+9t+7p)(modp), where t is a rational p-adic integer, [x] is the greatest integer not exceeding x and (ap) is the Legendre symbol. As consequences we determine P[p4](t)(modp) in the cases t=−53,−79,−6563 and confirm many conjectures of Z.W. Sun.
