In Exercises 1–20, evaluate each expression, or state that the expression is not a real number. ___ √-36

Simplify the following expression if possible otherwise state that it is a non-real number where we have the square root of negative 49 with possible answers seven negative 7, 1/7 or a non real number. So with the square root of -49, now something to keep in mind is we cannot have a negative on the radical for a square root. Here we notice we have a square of negative 49 because we have that negative another radical. We're gonna have a non-real answer. So we will say this is a non real number because of our negative. This means the answer to our problem is the answer D OK. I hope to help you solve the problem. Thanks for watching. Goodbye.
