Calculate the square of 1*(-3)-(-one second) to the 2003 power *(-2) to the 2002 power divided by two ninths

Calculate the square of 1*(-3)-(-one second) to the 2003 power *(-2) to the 2002 power divided by two ninths

The square of 1*(-3)-(-1/2) to the power of 2003*(-2) to the power of 2002 divided by two ninths
=2003 Power of 1*(-3)-(-1/2)*(-2)2002 power ÷2/9
=3-(-1/2)×(-1/2)2002 Power ×(-2)2002 power ÷2/9
=-3-(-1/2)×[(-1/2)×(-2)]2002?2/9
=3-(-1/2)×1 To the power of 2002÷2/9
=-3-(-1/2)×1÷2/9
=-3+1/2÷2/9
=-3+1/2×9/2
=-3+9/4
=-3/4

2003 Power of minus one-half multiplied by 2002 power of minus two Minus one-half of the 2003 power by minus two of the 2002 power Minus one-half the power of 2003 times minus two the power of 2002

= Minus one-half times minus one-half to the 2002 power, minus two to the 2002 power
= Negative half times (negative half times negative two) to the 2002 power
= Minus one-half multiplied by one to the 2002 power
= Negative half
