You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

If by "radical" you mean "square root of", then yes. Both square roots of 25 are real numbers.


What is radical number?

Another word for square roots is "radicals" which are the opposite operation of exponentiation; You undo a power with a radical, and a radical can undoes a power. For example: 4 is 22 so the square root or radical of 4 is 2.


Meaning of radical equation?

It is an equation containing a fractional power. Square roots and cube roots are typical examples but any fraction - positive or negative - will result in a radical equation.

What does radical mean in mathematics?

A radical is the sign √ which is used to indicate that a root must be calculated. The full format is n√ which indicates that it is the nth root that is required. For square roots the prefix is usually excluded. [As a result many people wrongly assume that the radical sign refers only to square roots.]

What are radical terms?

A "radical" equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root. The "radical" in "radical equations" can be any root, whether a square root, a cube root, or some other root. Most of the examples in what follows use square roots as the radical, but (warning!) you should not be surprised to see an occasional cube root or fourth root in your homework or on a test.


What is the square root of 126 in simplified mode?

The simplified radical expression of 126 is 3 roots of 14. 126 can be divided by the perfect square nine, fourteen times. As a result you have 3 roots of 14.

What is radical 14 times radical 2?

radical(14)*radical(2) = 2*radical(7) Without further information available we will consider only the square roots. The square roots of 14 are +3.741 and -3.741, similarly the square roots of 2 are+1.414 and -1.414 and so we can have four products 1) (+3.741) X (+1.414) = +5.155 2) (-3.741) x (+1.414) = -5.155 3) (+3.741) x (-1.414) = -5.155 4) (-3.741) x (-1.414) = +5.155 Expressions 1 and 4 are equal, expressions 2 and 3 are equal. Hence the product of radical 14 times radical 2 can be +5.155 or -5.155


What can you conclude about the square roots of numbers that are not perfect squares?

You cannot conclude anything.2.25 is not a perfect square but its square roots are +/- 1.5 so it is perfectly possible for a number which is not a perfect square to have a rational square roots.
