Question

√-80 Simplify

Answer 1

No answer....you cannot take the square root of a negative number (unless you're dealing with imaginary numbers already, but I don't think you are quite yet)

Answer 2

Yea we are actually lol im 17 and a junior in high skool..but i just get confused when it comes to imaginary numbers

Answer 3

Oh okay...well do it normally as if that 80 was positive

simplify that...you know 16 times 5 is 80..

so √16 √5

you know the √16 is 4

so you have

4√5

BUT this is IMAGINARY! because this is of √80 not √-80

so your answer will be

4i √5

Answer 4

thank you
