so, on my homework, i'm doing square roots. help?

Question

my homework says 'Find all the square roots of the number or write no square roots'

Number 26 is the problem -25 . That's all it says.
Now I'm not asking for the answer.

If the problem is -25 is the answer 'no solution'?

I'm not sure so that's why I'm asking. I -think- it's no solution. I think so because the square root of -25 on my calculator says 'DOMAIN error'.

And when I divided -25 by 5, I got -5 right? But it wouldn't work because -5 * -5 equals a positive 25, not negative (like it's suppose to be) And since on my calculator, it said DOMAIN error when i typed in the square root of -25, in other words that means there's no square roots right?

I tried to explain the best way I could.

I hope someone can help.

Thanks

Answer 1

yes, you are right, there is no square root of -25

the reason you get "Error Domain" on your calculator is that you can't take the square root of a negative number

to get a negative number, you have to multiply a positive by a negative, such as 5 * -1

i doubt you need to know this, but i'll tell you because all these people are saying the answer is 5i

i is the "imaginary number"
i = the square root of -1

so in your problem, find the square root of -25, you take the squareroot of 25 and the square root of -1, so you get 5i

Answer 2

when a negative is under the square root, you can take out the square root of -1 out and make that its own square...so you will have the square root of +25 and the square root of -1. now the square root of -1 can turn into an " i "(terms of i)...25's square is 5 so the answer would be 5 i.........at least im pretty sure lol

Answer 3

I am not sure how advanced you are in algebra. If it says to give the square root or write no square roots, I would assume you are not working with imaginary numbers.

The anwser is either 5i or no square roots.

Without the use of imaginary numbers, a negative number will always be "no square roots"

Answer 4

You are correct, there are no solutions to square rooting a negative number. However, at degree level you will actually discover that there are square roots of negative values - these are called imaginary numbers. I'm guessing you're not at degree level so you don't need to know this much.
But tell you're teacher and stand out from other students who will look amazed (cough cough) lol

Answer 5

Oh yes, this is my strong point. If you are in algebra 1, then write no square roots. If you are in algebra 2 or higher then write 5i. "i" stands for imaginary, meaning it is not a real number. "i" means the square root of negative one. Therefore, 5i means five square roots of nagative one. Now go impress your math professor with that information.

Answer 6

there is no square root for -25 write no square roots
also i have a 100% in my AP algebra class

Answer 7

16 situations 5 = 80: both aspects are 16 and 5. we are able to take the sq. root of 16 is 4. we received't component 5 calmly so it might want to proceed to be lower than the unconventional signal. Your answer is 4 situations the sq. root of five. the answer is: 4 situations( 2.236 ) to three decimal places. sq. root 5 = 2.236

Answer 8

The answer is 5i.

Click mode on your calculator and switch real numbers to a+bi form, than it will recognize the problem.

Answer 9

im pretty sure the answer is 5 that was the answer on my calculator anyways i dont know why. but it is

Answer 10

Just skip it and ask The teacher tommorow, or just do like i do and copy off the smart kid! but honestly just ask yur teacher, she would b more than happy to help.... : )
