Answer:

Step-by-step explanation:

√(-245)=√(49×5×i^2)=7√5 i=0+7√5 i

Answer:

[tex]\sqrt{-245}[/tex]  in the form a + bi is [tex]0+7\sqrt{5}i[/tex]

Step-by-step explanation:

We know that

       [tex]i=\sqrt{-1}[/tex]

We need to find  [tex]\sqrt{-245}[/tex]

     [tex]\sqrt{-245}=\sqrt{-1}\times \sqrt{245}=i\sqrt{245}=i\sqrt{49\times 5}=i\times 7\sqrt{5}[/tex]

[tex]\sqrt{-245}[/tex]  in the form a + bi is [tex]0+7\sqrt{5}i[/tex]
