The causes of back pain are nearly as numerous as terms used to describe the symptoms. Back pain is a primary reason people seek medical attention. Considering that almost 80% of the adult population will encounter some form of back pain, it could be said that back pain is a universal epidemic.
Multiplicity of a root of a polynomial[edit] Let F be a field and p(x) be a polynomial in one variable and coefficients in F. An element a â F is called a root of multiplicity k of p(x) if there is a polynomial s(x) such that s(a) â  0 and p(x) = (x â a)s(x).
If you use a calculator to find â15, for example, will give you 3.872983346207417.... You can also find square roots of fractions. For example, because 2 / 3 x 2 / 3 = 4 / 9, 2 / 3 is a square root of 4 / 9. An easy way of looking at this is looking at the square roots of the numerator and denominator separately. Example: Find â 25 / 36. Solution: Because the square root of 25 is 5, and teh square root of 36 is 6, then the square root of 25 / 36 = 5 / 6.
