Explanation:

To find the polar form of the expression (2cis60°)(5cis30°), we can multiply the magnitudes and add the angles.

The magnitude of the product is obtained by multiplying the magnitudes of the individual complex numbers:

Magnitude = 2 * 5 = 10

The angle of the product is obtained by adding the angles of the individual complex numbers:

Angle = 60° + 30° = 90°

Therefore, the polar form of (2cis60°)(5cis30°) is 10cis90°.
