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]
