Simplify the expression.−5+i2i

Answer 1

First, let's simplify i^2:
i^2 = -1

Next, let's rewrite the expression with the simplified i^2:
-5 + i(2i) = -5 + 2i^2

Now, substitute -1 for i^2:
-5 + 2i^2 = -5 + 2(-1)

Simplifying further:
-5 + 2(-1) = -5 - 2 = -7

Therefore, -5 + i(2i) simplifies to -7.
