Explicação passo a passo:

$\mathsf{z_1 = 4 + 2i}$

$\mathsf{z_2 = 3 + 4i}$

$\mathsf{z_1 + z_2 = (4 + 2i) + (3 + 4i)}$

$\mathsf{z_1 + z_2 = (4 + 3) + (2i + 4i)}$

$\boxed{\boxed{\mathsf{z_1 + z_2 = 7 + 6i}}}$

$\mathsf{z_1 \times z_2 = (4 + 2i) \times (3 + 4i)}$

$\mathsf{z_1 \times z_2 = 12 + 16i + 6i + 8i^2}$

$\mathsf{z_1 \times z_2 = 12 + 16i + 6i + 8(-1)}$

$\mathsf{z_1 \times z_2 = 12 - 8 + 16i + 6i}$

$\boxed{\boxed{\mathsf{z_1 \times z_2 = 4 + 22i}}}$
