a= +2- 5+ 8- I+2I b=I5- 8I+ I5- 4I- I9- 1I+ I13-16I
a=+2- 5+ 8+ 2 b=I -3I+ I+1I- I+8I+ I -3I
a= -3+ 8+ 2 b= +3+ 1- 8+ 3
a= +5+ 2 b=+4- 8+ 3
a= +7 b=- 4+ 3
b= -1
c=I-7I+ I2³- 3²I- I3³- 5²I d= -8-I-12I+ I-6²+ 5²I- I-7+ 2³I
c= +7+I8- 9I- I27-25I d= -8-12+I-36+25I- I-7+8I
c= +7+ 1- 2 d= -8-12+11- 1
c= +8- 2 d= -20+11- 1
c= +6 d= -9- 1
d= -10
