Obtain fifth roots of 4 3i?
To find the fifth roots of 4 + 3i, first convert the number to polar form: 4 + 3i = 5∠36.87°. Then, to find the fifth roots, divide the angle by 5: 36.87° / 5 = 7.374°. The fifth roots in polar form are 5∠7.374°, 5∠67.374°, 5∠127.374°, 5∠187.374°, and 5∠247.374°.
How does the sign of a determine the number of real fourth roots of a and the number of real fifth roots of a?
If "a" is positive, it will have two fourth roots, one will be positive and one will be negative it will have one fifth root, which will be positive. If "a" is negative, it will have one fourth root, which will be negative. it will have one fifth root, which will be negative.
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.

How many fifth roots does 243 have?
The number 243 can be expressed as (3^5). When finding the fifth roots of a number, we consider the equation (x^5 = 243). In the complex number system, any non-zero number has five distinct fifth roots, so 243 has a total of five fifth roots, which are evenly spaced on the complex plane.
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.
