Friends, simplifying radical expressions is not an easy task. If the expression comes with decimal values or expression with a large number then it is quite difficult to find the root of the same value. Now today we are going to learn about the concepts behind radicals and how to simplify radicals. For simplifying such type of expressions various Simplify Expressions Calculator are available online which solves radical expressions in a faster manner and provides an exact answer for the same. It works by separating out multiples of the radicals that have integer roots. The expression calculators calculate or simplify radicals of positive integers, while decimals will be rounded up.
First question comes in our mind is that what is a radical? Radical is known as root of an expression. A fraction is not a radical, but a fraction may contain a radical. It uses the sign of radical (√) also known as surds. Let's take an example to understand it better. A radical equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root.
The square of 2 = 4 it means 2 is the square root of four. 2³ = 8 this means 2 is the cube root of 8. if a, b are real numbers, n is a positive integer and if an = b then the n th root of b is a. then it can be written in this form : n root b = a
In n root b, n is the index and b is the radicand. The index gives the degree of the roots.
For example : Root x + 2 = 4
root x = 4
root x = 22
x = 2
The steps to solve radical problems are : break or isolate the radicals to the left side of equal sign means get one radical on one side and everything else on the other using inverse operations. . Then square each side of the equation and solve the equation we get all the solution.
A number that can be represented as the ratio of two numbers known as fractions. For example : ½
here 1 is numerator and 2 is denominator. The condition for fraction is that denominator can never be a zero.
Now the question arises that how to Simplify Fractions? For simplifying fractions following are some rules:
Adding and Subtracting of a fraction is done by using this property: x/y + a/b = xb + ay / yb.
For Multiplying a fraction this property comes in an account: a/b x c/d = ac/bd
and for dividing a fraction we use this property: a/b divide c/d = ad/bc.
