Question

1+2i/1-3i ka mapank air kodank bataiye​

Answer 1

Answer:

√2/2

Step-by-step explanation:

If z = x + yi , then | z | = √(x² + y²)

$\frac{1+2i}{1-3i} *\frac{1+3i}{1+3i}$ = $\frac{(1+2i)(1+3i)}{10}$ = $\frac{1+5i-6}{10}$ = $\frac{i-1}{2}$ = - 0.5 + 0.5i = z

| z | = √[(- 0.5)² + (0.5)²] = √0.5 = √2/2
