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.

How is combining like terms similar to adding and subtracting 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.


What is simplest radical form?

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.

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 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 is a radical equation?

They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside... Ex. sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7) sqrt(28) = 2 * sqrt(7)
