A radical equation is one that involves square root (or possibly other roots eg. cube roots, etc.).

it the number that is simfilied

an alg expression involving square roots, cube roots, etc

Simplest radical form means simplifying a radical so that there are no more square roots, cube roots, 4th roots and such left to find. It also means removing any radicals in the denominator of a fraction.

The answer depends on "different from WHAT?" Positive cube roots, or negative square roots?

In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.

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

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.

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.

A radical is the sign âˆš which is used to indicate that a root must be calculated. The full format is nâˆš 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.]

30.06659 or if you leave it as a radical its 2 sq roots of 226

Square roots of negative numbers ARE possible. I guess you haven't been introduced to "imaginary numbers" and the letter "i".

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.

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.

Radical roots

7 and -7.

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

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.

There are two possible answers because if you square a negative number, you will get a positive answer.

radical equations have sq roots, cube roots etc. Quadratic equations have x2.

Replace the radical sign with the exponent 0.5. For example sqrt(7) = 70.5

The square root of 15 is simply root 15, since neither 3 nor 5, 15's only factors, have square roots.
