The answer is 60 and 240 degrees.
Add radical 3 and inverse tan to get answer add 180 for other answer less than 360.
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
radical equations have sq roots, cube roots etc. Quadratic equations have x2.
When in doubt always square both sides of the equation.
You don't. If the negative sign is outside the radical, then you take the square root of the number and apply the negative. If the negative sign is inside the radical, you will have an imaginary number.

A radical equation is an equation that contains a variable inside a radical, such as a square root or a cube root. Solving radical equations involves isolating the radical term and then squaring both sides of the equation to eliminate the radical. It is important to check for extraneous solutions when solving radical equations.
Radical...Apex :)
You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
easy, lets take radical negative 3 for example. you can take out a "i" because i = the radical negative one. There fore the answer is i radical 3.
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
Square both sides of the equation to get rid of the radical sign. Then just solve as you normally would. Good luck! :-)

It often helps to isolate the radical, and then square both sides. Beware of extraneous solutions - the new equation may have solutions that are not part of the solutions of the original equation, so you definitely need to check any purported solutions with the original equation.
When in doubt always square both sides of the equation.
Tin ions are positive (cations).
2i radical 5 * * * * * No. it is ± i*radical(25) which is ± 5i. Not sure why the answer is requireed in radical form.
