multiply the two z₁= [3,52⁰] and z2 = [2, 15°]

To multiply the two complex numbers given in polar form:

Given:
- \( z_1 = [3, 52^\circ] \)
- \( z_2 = [2, 15^\circ] \)

The product of two complex numbers in polar form is given by:
\[
z_1 \times z_2 = [r_1 \times r_2, \theta_1 + \theta_2]
\]

Where:
- \( r_1 \) and \( r_2 \) are the magnitudes
- \( \theta_1 \) and \( \theta_2 \) are the angles

**Step 1: Multiply the magnitudes:**
\[
r_1 \times r_2 = 3 \times 2 = 6
\]

**Step 2: Add the angles:**
\[
\theta_1 + \theta_2 = 52^\circ + 15^\circ = 67^\circ
\]

So, the product is:
\[
z_1 \times z_2 = [6, 67^\circ]
\]

### Result:
\[
z_1 \times z_2 = [6, 67^\circ]
\]
