You'll want to read the documentation for these two functions again:

void mpz_sqrt (mpz_t rop, mpz_t op)

  Set rop to the truncated integer part of the square root of op.

void mpz_sqrtrem (mpz_t rop1, mpz_t rop2, mpz_t op)

  Set rop1 to the truncated integer part of the square root of op,
  like mpz_sqrt. Set rop2 to the remainder op-rop1*rop1, which will be
  zero if op is a perfect square.

  If rop1 and rop2 are the same variable, the results are undefined.
