I cant use the square root symbol so lets use the word "root" to represent square root. The answer would be 4root2
To use the root button on a scientific calculator, first type the number you want to find the root of. Then, press the root button, which is usually denoted by a √ symbol. Finally, enter the index of the root, such as 2 for a square root or 3 for a cube root, and press equals (=) to get the result.
-13 or +13 are both square root of 169, but we often use the positive square root, 13, as the principal square root.
No, you can also use conjugates with more than one radical term. For example, if the denominator is root(2) + root(3), you can use the conjugate root(2) - root(3) to rationalize the denominator.
