  1. – a 2 = ( –1 ) ( a 2 ) = –1 a =ai
  2. –2 = ( –1 ) ( 2 ) = –1 2 = 2 i
  3. 2 –9 =2 – 3 2 =2 ( –1 ) ( 3 ) 2 =2.3 –1 =6i
  4. –81 = – 9 2 =3 –1 =3i
  5. –6 = ( –1 ) ( 6 ) = –1 6 = 6 i
  6. 3 – b 4 =3 ( –1 ) ( b 4 ) =3 b 2 –1 =3 b 2 i
  7. –12 = ( –1 ) ( 2 2 ) ( 3 ) =2 –1 3 =2 3 i
  8. –7 = ( –1 ) ( 7 ) = –1 7 = 7 i
  9. –27 = ( –1 ) ( 3 2 ) ( 3 ) =3 –1 3 =3 3 i
  10. –4 m 4 = ( –1 ) ( 2 2 ) ( m 4 ) =2 m 2 –1 =2 m 2 i
  11. – 1 16 = ( –1 ) ( 1 4 2 ) = 1 4 –1 = 1 4 i
  12. – a 2 – b 2 = –( a 2 + b 2 ) = ( –1 ) ( a 2 + b 2 ) = –1 a 2 + b 2 = a 2 + b 2 i
