Question

Write the following as a complex number in the form a + bi square root -245

Answer 1

Explanation:

√(-245)=√(49×5×i^2)=7√5 i=0+7√5 i

Answer 2

`√(-245)` in the form a + bi is
`0+7√(5)i`

Explanation:

We know that

`i=√(-1)`

We need to find
`√(-245)`

`√(-245)=√(-1)* √(245)=i√(245)=i√(49* 5)=i* 7√(5)`

`√(-245)` in the form a + bi is
`0+7√(5)i`
