How do you simplify fourth roots?
The answer will depend on the form of the fourth root. Positive real numbers will have two fourth roots which are real and two that are complex. Complex numbers will have four complex roots. However, none of these can be "simplified" in the normal sense of the term.
What is the fourth root of 11?
Two of the four roots are 1.8212 and -1.8212 (approx). The other two roots are complex numbers.
How many cubed roots are there in number 27?
There are 3 cube roots of 27. There are 2 square roots of 27 ( or any real number ). There are 4 fourth roots of 27 and so on:)
How many fourth roots will a positive real number have?
In general, the answer is 4, but only 2 of them are real. For example, the 4th roots of 16 are 2, -2, 2i, and -2i.
What numbers are surds?
They are numbers that are formed by linear combinations of square roots, cube roots (and other higher roots) of numbers which cannot be simplified into ratios of integers (ie rational numbers). The linear combinations may also contain integers. A linear combination is simply a way of saying so many sqrt(2)s plus that many cuberoot(7)s etc.

What are the fourth roots of 1 plus you?
There are no roots - fourth or otherwise - of 1 plus me!
What are all the real fourth roots of 0.0081?
The real fourth roots are -0.3 and 0.3
What is the fourth root of 91?
The four numbers are:3.0886,-3.0886,3.0886*i and-3.0886*iwhere i is the imaginary square root of -1.The first two roots are real numbers.
At most, how many unique roots will a fourth-degree polynomial have?
Four.Four.Four.Four.

How do you multiply and divide expressions with square roots?
The rule you can use is that root(a) x root(b) = root(ab), or root(a) / root(b) = root(a/b). This rule works for real numbers, but if you ever have to handle complex numbers, it is no longer valid. In the case of real numbers, it also works with cubic roots, fourth roots, etc.
Which set of numbers does -3 go into?
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.
At most how many unique roots will a fourth degree polynomial have?
4, the same as the degree of the polynomial.
How many real roots can a fourth degree polynomial have?
Upto 4. If the coefficients are all real, then it can have only 0, 2 or 4 real roots.
What number sets does -8 belong to?
To any set that contains it! It belongs to {-8}, or {-8, sqrt(2), pi, -3/7, 99.3}, or all whole numbers between -43 and 53, or multiples of 2, or integers, or rational numbers, or real numbers, or complex numbers, or square roots of 64 or fourth roots of 4096 etc.
