16.
How do you find the square root of 256?

Simplify the square root of 512?
The idea is to take out perfect squares. The largest perfect square in this case is 256, which is the square of 16 (if you have trouble figuring this out, you can take out a smaller perfect square first, and then see if you find additional perfect squares). In any case, the end result should not have a factor that is a perfect square. Using the symbol "root()" for square root: root(512) = root(256 x 2) = root(256) x root(2) = 16 root(2)
What is the square root of 280?
It has no pure square root. 16 x 16 =256 but this leaves a remainder of 24.
Is the square root of 266 irrational?
162 is 256 and 172 is 289, so YES, √266 is irrational
Is the square root of a decimal always an irrational number?
Not necessarily. The square root of 2.56 equals 1.6, and the square root of 0.25 equals 0.5, for two examples. If the decimal represents a rational number that is a fraction of two perfect squares, then the square root will be a rational number. The two examples I gave were 2.56 = 256/100, and 0.25 = 1/4.

Yes.
Is 2.56 irrational?
No, irrational numbers must continue past the decimal indefinitely, without a pattern, and can't be expressed as a fraction. Not only does 2.56 stop at the hundredth decimal, but it can also be expressed as the fraction 256/100. Its worth noting that 1.999999...forever repeating is also a rational number. Irrational numbers are usually things like pi, the square root of two, etc.
Fourth root of 256?
4th root is same as square root of square root: sqrt(256) = 16, and sqrt(16) = 4
