Question

question 4
part a

enter the correct answer in the box.

rewrite the expression \\(\frac{4 + \sqrt{16 - (4)(5)}}{2}\\) as a complex number in standard form, \\(a + bi\\).

Explanation:

Simplify the radical term

$$ \sqrt{-16} = \sqrt{16} \cdot \sqrt{-1} = 4i $$

Substitute and simplify the expression

Write in standard form \(a + bi\)

$$ (2 - 20) + 2i = -18 + 2i $$

Answer:

Rewrite the expression \(\frac{4 + \sqrt{-16}}{2} - (4)(5)\) as a complex number in standard form, \(a + bi\).
