Question

`x2 = (9)/(256)`
I don't understand this at all ​

Answer 1

It is an equation, telling you that left side of = is same as right side and asking you to solve it (figure out the x).

`x^2=(9)/(256)`

Apply square root on both sides of the equation to get rid of power on x.

`x=\pm\sqrt{(9)/(256)}`

Now simplity the square root.

`x=\pm(√(9))/(√(256))=\boxed{\pm(9)/(16)}`

Hope this helps.
