Question

Write the number in the form a + bi. √(-4)+10

Answer 1

Answer:

10  +  2i

Step-by-step explanation:

√−4 + 10

Simplify each term.

Rewrite

√−1(4) + 10

√−1 ⋅ √4 + 10

Rewrite  √−1  as  i

i  ⋅ √4 + 10

i  ⋅ √2^2 + 10

Pull terms out from under the radical, assuming positive real numbers.

i  ⋅ 2 + 10

2i  +  10

or

10+2i
