Question

sqrt root of -$423751.822100314
my calculator gave me error

nikato · Answer

Because calculators can't do square root of a negative number

anonymous · Answer

ok.. how do you figure out then?

nikato · Answer

So sqrt of -1 is i
Then just find the square root of the number

anonymous · Answer

mmm...

nikato · Answer

And you don't have to plug in -. Since you "took it out"

So you're looking at sqrt of -1 times sqrt of 423751.822...

anonymous · Answer

oh.. so i get rid of - ?

anonymous · Answer

$$\sqrt{423751.822100314} $$ You have to take out the - to be able to find the square root. Once you do that solve the problem, which equals to 650.962

Now that you have the answer you will place an "i" behind the number. You do this with all negative numbers that you are trying to get the square root out of.

So your answer is 650.962i
