Answer:
Step-by-step explanation:
The expression
can be rewritten as a complex number in standard form as 4 + i.
To rewrite the expression
as a complex number in standard form a + bi, we need to simplify the expression inside the square root and then perform the necessary calculations.
The expression inside the square root is 16 - (4)(5) = 16 - 20 = -4. Since we have a negative value inside the square root, we can rewrite it as 2i√{1} to simplify it.
Now, let's rewrite the expression:
Since √{1} = 1, the expression becomes:
4 + i√{1} = 4 + i
Therefore, the expression
can be rewritten as a complex number in standard form as 4 + i.
