Purely real numbers (a+0i)

  • -1 +0i
  • -5+0i
  • -12+0i
  • 9+0i

Non-real complex number (0+bi)

  • 1-i
  • 7-5i
  • 0+i√6
  • 0+9i

What are Purely real numbers and Non-real complex numbers?

Purely real numbers are in the form of a+0i, while the Non-real complex numbers are in the form of a+bi.

The given expressions can be simplified in the following manner,

  • [tex]-i^{2} +1^{3} =-(\sqrt{1)} ^{2} +\sqrt{-1}[/tex] x [tex]\sqrt{-1}[/tex] x[tex]\sqrt{-1}[/tex] ) = 1 - i
  • 7 - 5i
  • [tex]\sqrt{-6} = \sqrt{-1(6)} =\sqrt{-1} (\sqrt{6} )=0+i\sqrt{6}[/tex]
  • [tex]i^{6} =(i^{2} )^{3} =(-1)^{3} =-1=-1+0i[/tex]
  • 0 + 9i
  • [tex](\sqrt{-5} )^{2} =(\sqrt{-1(5)} ^{2} = -1 (5)=-5+0i[/tex]
  • - 12 = -12 + 0i
  • [tex]2-7i^{2} =2-7(-1)=2+7=9+0i[/tex]
