Firstly it depends on what root is present. Then you have to equate so that the variable is present at one side and constant at the other side. Like for example:
cube root(x)+50=60
cube root(x)+50-50=60-50
cube root(x)=10
Now cube the whole thing
x=(10)^3
x=1000

∙ 10y agoYou can only subtract (or add) radicals if they are to the same base. In that case, you treat the radical part as you would a letter-variable in an algebraic expression.
So, just as 5x - 3x = 2x you have 5√2 - 3√2 = 2√2.
Sometimes, you may to simplify the radicals to make the bases equal. For example:
3√8 - 4√2 = 6√2 - 4√2 = 2√2

∙ 11y agoA radical is also known as a 'Square root' of a number. The objective is to get the radical to it's lowest term.
First you'll have to know the basic perfect squares:
1
4(2x2)
9(3x3)
16(4x4)
25(5x5)
36(6x6)
49(7x7)
64(8x8)
81(9x9)
100(10x10)
121(11x11)
144(12x12)
169(13x13)
196(14x14)
After you've acknowledged those you can simplify radicals.
examples:
(Beginner)
√9 = 3
√64 = 8
√81 = 9
(More difficult)
√8 = ?
8 is not a perfect square so you will need to use factors.
√8 = √4 times √2
Then you know that 4 is a perfect square and simplifies to 2.
Your answer will be 2 √2.

What property of the square root is essential in order to solve any radical equation involving a square root?
The property that is essential to solving radical equations is being able to do the opposite function to the radical and to the other side of the equation. This allows you to solve for the variable. For example, sqrt (x) = 125.11 [sqrt (x)]2 = (125.11)2 x = 15652.5121
