The 4th root of 256 is 4
0.0625 has a grand total of 2 square roots, and they're both real. They are +0.25 and -0.25
.06 and .06
( +0.063246 ) and ( -0.063246 ).These numbers are rounded.These are the only square roots of 0.004. There are no more real ones,and no imaginary or complex ones.
sqrt(0.0004) = +/- 0.02. Try calculating (+0.02)^2 and (-0.02)^2 by hand to convince yourself that both are real roots of 0.0004. ================
To any set that contains it! It belongs to {-3}, or {45, sqrt(2), -3, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 3, or integers, or rational numbers, or real numbers, or complex numbers, or square roots of 9, of fourth roots of 81, etc.
The real fourth roots are -0.3 and 0.3
Upto 4. If the coefficients are all real, then it can have only 0, 2 or 4 real roots.

A quadratic function can have up to two roots. Depending on the discriminant (the expression under the square root in the quadratic formula), it can have two distinct real roots, one repeated real root, or no real roots at all (in which case the roots are complex). Therefore, the total number of roots, considering both real and complex, is always two.
.06 and .06
They are 0.5 : it is a triple root.
( +0.063246 ) and ( -0.063246 ).These numbers are rounded.These are the only square roots of 0.004. There are no more real ones,and no imaginary or complex ones.
