a.) Write down the formulas for all homomorphisms from Z10 into Z25.
b.)Write down the formulas for all homomorphisms from Z24 into Z18.
c.)Write down the formulas for all homomorphisms from Z into Z10.
d.)Extra: Define φ : C x → Rx by φ(a + bi) = a 2 + b 2 for all a + bi ∈ C x where R is the real numbers and C is the complex numbers. Show that φ is a homomorphism.
