Problem solving process: 1, the (-2) power of 2002 = the second power of 2002 Reason: The even power of a negative number is equal to the even power of its opposite number.

2,2 and 0.5 are reciprocal relations, so there is the following calculation process:

(-2) 2002 * 2003 (0.5) = 2 2002 * 2003 (1/2).

Power of 2002 = 2 * Power of 2002 (1/2) *( 1/2)

Power of 2002 =[2*( 1/2)] *( 1/2)

= 1 to the power of 2002 *( 1/2)

= 1/2.
