Yes.
Definitely RATIONAL. sqrt(2.56) = 1.6 NB Irrational numbers are those were the decimals recur to infinity and there is no regular order in the decimal digits. 1.6 is a terminating decimal and does NOT recur to infinity, then it is NOT irrational.
256 is an integer and not a fraction. However, it can be expressed in rational form as 256/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
256 square meters = 2,755.56 square feet (rounded)
is a square a rational symmetry? is a square a rational symmetry?
There are no real square roots of -256. But using complex numbers the square roots of -256 are 16i and -16i.
256 has two square roots: 16 and -16.
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.
16 or -16The square root of 256 is 16. 16
Answer: 256 m² = 2,755.561 ft²
Answer: 256 ft² = 23.7831 m²
Yes. 256 = 162
A non-square rational number is a rational number that cannot be expressed as the square of any rational number. For example, ( \frac{2}{3} ) is a non-square rational number because there are no rational numbers whose square equals ( \frac{2}{3} ). In general, any rational number that does not have a perfect square as its numerator and denominator is considered a non-square rational.
