When adding the square root of 16 and -8 which type of number is the Sum

Integer
Irrational number
Radical
Whole number

2 answers

The sum of the square root of those two numbers would be a complex number. Therefore it can't be an integer or an irrational number (irrational numbers are real numbers). It certainly isn't a whole number.

I'd say the best choice out of the four you've given is a radical, but complex number would be the ideal choice.
thank you so much
