There are three steps on how to evaluate a radical. Some of the step-by-step instructions are multiply two radicals with the same index number by simply multiplying the numbers beneath the radicals, divide a radical by another radical with the same index number by simply dividing the numbers inside, and simplify large radicals using the product and quotient rules of radicals.

It depends on what you mean by solve: simplify, evaluate or rationalise the denominator. The answer will also depend on the radical expression.

There is no reasonable radical approximation for radical 11.

Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.

Radical (3x) = radical(x) * radical(3).

A stable radical is a radical that is not changing. A radical is a molecule or atom that has an unpaired electron.

-3*radical(2)*radical(50) = -3*radical(2*50) = -3*radical(100) = -3*10 = -30

a radical b or -a - radical b

radical 30

Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30

98

Radical 147 simplified is 7 radical 3. radical147= radical 49* radical 3 the square root of 49 is 7 therefore the answer is 7 radical 3
