Solution :
We know, square root of negative real number is imaginary.
Taking square root of the number i.e, [tex]\sqrt{-1.44}[/tex]
[tex]\sqrt{-1.44}=\sqrt{-1\times 1.44}[/tex]
[tex]\sqrt{-1.44}=\sqrt{-1}\times \sqrt{1.44}[/tex]
[tex]\sqrt{-1.44}=i\times 1.2[/tex]
[tex]\sqrt{-1.44}=1.2i[/tex]
Therefore, The answer is [tex]\sqrt{-1.44}=1.2i[/tex]
