They are 0.5 : it is a triple root.
The real fourth roots are -0.3 and 0.3
-0.07 and +0.07
It is 15, -15.
One cubic root is -2. The other two are complex numbers - all have the same absolute value, and they are at an angle of 120 from one another. Since -2 = 2 at an angle of 180°, the other two cube roots are 2 at an angle of 60°, and 2 at an angle of -60°. Use your calculator's polar-to-rectangular conversion to separate this into the real and imaginary components, if you want to present the answer that way.
Personally I prefer to convert roots to fractional powers for this kind of problem. cube root of x squared is x2/3, and square root of x is x1/2. Adding the exponents, you get x2/3 times x1/2 = x7/6, that is, the sixth root of x to the seventh power - where it doesn't matter whether you take the sixth root first, or raise to the sevents power first. Alternatively, you can convert all roots to sixth roots, and multiply - and of course, get the same result.
All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.
In mathematics, a cube root of a number, denoted or x1/3, is a number a such that a3 = x. All real numbers (except zero) have exactly one real cube root and a pair ofcomplex conjugate roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8 is 2, because 23 = 8. All the cube roots of −27iareThe cube root operation is not associative or distributive with addition or subtraction.The cube root operation is associative with exponentiation and distributive with multiplication and division if considering only real numbers, but not always if considering complex numbers, for example:but
What does this question mean? -60 has a real cube root, a real fifth root. In fact a real nth root for all odd n.
No, the vast majority are not.
The real fourth roots are -0.3 and 0.3
-0.4
Upto 4. If the coefficients are all real, then it can have only 0, 2 or 4 real roots.
0.0625 has a grand total of 2 square roots, and they're both real. They are +0.25 and -0.25
5210. - .0125 = 5209.9875 A decimal does not have to be smaller than 0 so 5210 IS a decimal.
-0.07 and +0.07
