Question

2 times the square root of 25 plus the square root of negative 16

Answer 1

10+4i

Explanation:

2*√25 + √-16.

Given

2*5+4i

Simplify the sqrts. If you are wondering where I got "i" from, "i" is √-1. "i" is short for imaginary number because there is no real number that can be a square root of a negative number. I got the 4 because it is the square root of -16

10+4i

I multiplied the 2 and the 5. This is the simplest form because you cannot add imaginary and real numbers together.

Answer 2

10 + 4 i
