The formulas of the compounds formed by NH4+ with the following anions are as follows:

1. NH4CN (Ammonium cyanide): NH4+ + CN-
2. NH4ClO3 (Ammonium chlorate): NH4+ + ClO3-
3. (NH4)2SO4 (Ammonium sulfate): 2(NH4+) + SO42-
4. (NH4)2HPO4 (Ammonium dihydrogen phosphate): 2(NH4+) + H2PO4-

To write the formulas of compounds formed between NH4+ (ammonium ion) and the given anions, you need to consider the charges of each ion and balance them to form a neutral compound.

1. NH4+ with CN- (Cyanide ion):
The ammonium ion has a charge of +1, and the cyanide ion has a charge of -1. To balance the charges, you need one ammonium ion and one cyanide ion. Therefore, the formula is NH4CN.

2. NH4+ with ClO3- (Chlorate ion):
The ammonium ion has a charge of +1, and the chlorate ion has a charge of -1. To balance the charges, you need one ammonium ion and one chlorate ion. Therefore, the formula is NH4ClO3.

3. NH4+ with SO42- (Sulfate ion):
The ammonium ion has a charge of +1, and the sulfate ion has a charge of -2. To balance the charges, you need two ammonium ions and one sulfate ion. Therefore, the formula is (NH4)2SO4.

4. NH4+ with H2PO4- (Dihydrogen phosphate ion):
The ammonium ion has a charge of +1, and the dihydrogen phosphate ion has a charge of -1. To balance the charges, you need one ammonium ion and one dihydrogen phosphate ion. Therefore, the formula is NH4H2PO4.

Remember to always balance the charges of the ions to form a neutral compound.
