Solving Radical equation formula
Radical equation formula : Any root, whether square or cube or the other root are often solved by squaring or cubing or powering each side of the equation with nth power. Squaring or cubing or powering each side of the equation with nth, will solve a radical equation. Actually there no formula for the novel equation to unravel it but if it’s n power then powering two sides by nth power gives the answer.
Let us consider an equation
x−−√n = c
Raise both the sides by nth power
(x1/n)n = cn
x = cn
Solved Example
Question:
Solve the radical : x−−√3=9
Solution
Given
x−−√3=9
(x13)3=93
x = 729
Definition of a Radical Expression equation formula
In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. many of us mistakenly call this a ‘square root’ symbol, and lots of times it’s wont to determine the root of variety . However, it also can be wont to describe a root , a fourth root, or higher. When the novel symbol is employed to denote any root aside from a root , there’ll be a superscript number within the ‘V’-shaped a part of the symbol. for instance , 3√(8) means to seek out the root of 8. If there’s no superscript number, the novel expression is looking for the root .
