What is your question?
Solve the equation. x^2=160
do you want a direct answer or explaintion
Explanation please.
^2 means an exponet, which you have multiply the number by the number it says for example: 3 3 3 3 3^4 = _____ x _____ x _____x _______ there are four places for the number three
in this case, _____ x ____ = 160
Solve x^2=160. One way would be to take the square root of both sides. Can y ou do that?
TheCleaverOne i ment square root
then just find the sme number that muliply together that equal that number
Mathmale it does not come out as a perfect square though.
you can round
12.64 is your answer
oh ok
Thank you!!! :D

True, 160 is not a perfect square. However, you can write Sqrt(160) as\[\sqrt{160}=\sqrt{10}\sqrt{16}\]
Note that 16 is a perfect square, so that the square root of 16 is easily found. What is your final result? Remember, this is a quadratic equation, so you MUST write out 2 roots. The roots of x^2-160=0 are: What?
4 and 10?
"care to fan and medal?" is not an appropriate request. See the Code of Conduct, please.
If x^2-160=0, then x^2=160 Taking the sqrt of both sides results in x = plus or minus Sqrt(10)*Sqrt(16). Yes, 4 is the sqrt of 16. Must leave sqrt(10) as is, since 10 is not a perfect square.
Can you help me with some more?
If you'll post them one by one, yes.
In general, the solution to \(x^2 = k\) where k is a number is \(x = \pm \sqrt k\) In your case, k = 160. Find the square root as you did above, but don't forget the negative solution also.
