what is taking square roots Taking the square root is figuring out what number multiplied by itself is equal to the number under the square root symbol So 4 2 because 2 2 OR 2 2 4 9 3 because 3 x 3 9 OR 3 2 9 Hopefully that helps
In mathematics a square root function is defined as a one to one function that takes a positive number as an input and returns the square root of the given input number f x x For example if x 4 then the function returns the output value as 2 Square Root Definition The square root of a number is the value of power 1 2 of that number In other words it is the number whose product by itself gives the original number It is represented using the symbol The square root symbol is called a radical whereas the number under the square root symbol is called the radicand

What does it mean to take the square root Taking the square root is a method used for solving quadratic equations in the form x 2 text constant It means to calculate the square root of both sides of the equation in order to get the solutions of the equation 2 years ago The first two steps are exactly like solving a two step linear equation Two step equations require you to add subtract first and then divide or multiply second If you have x 2 5 13 you subtract 5 on both sides to get x 2 8
The positive square root of a positive number is the principal square root We can estimate square roots using nearby perfect squares We can approximate square roots using a calculator When we use the radical sign to take the square root of a variable expression we should specify that x ge 0 to make sure we get the principal square root The Square Root Symbol This is the special symbol that means square root it is like a tick and actually started hundreds of years ago as a dot with a flick upwards It is called the radical and always makes mathematics look important We can use it like this and we say square root of 9 equals 3

The principal square root function usually just referred to as the square root function is a function that maps the set of nonnegative real numbers onto itself In geometrical terms the square root function maps the area of a square to its side length Example 1 Solve the quadratic equation below using the Square Root Method I will isolate the only latex x 2 latex term on the left side by adding both sides by latex 1 latex Then solve the values of latex x latex by taking the square roots of
