How do you simplify and multiply radicals?
The answer depends on what form of radicals: numbers with factors which are square numbers, radicals where the radicand is in the form of a ratio or a decimal number. Without more information it is not possible to give an answer.
What is the root of a number?
The root of a number is any number that when multiplied by a certain number of times, it becomes the original number. The number of times the root has to be multiplied is called the index of the radical. The number that it becomes after it is multiplied is called the radicand. If the index is equal to x, and the radicand is equal to y, then the root can be expressed by " y to the (1/x)th power", or "y1/x".
What is radicand?
-The radical is the symbol that represents a square root. -The radicand is the number underneath the radical symbol. -The coefficient is the number out in front of the radical. (We assume that the coefficient multiplies the radical, the same way it would multiply with a variable.)
The number or expression inside a radical symbol?
The term radicand means the number or expression inside the radical symbol. For example, when we have the square root of 2, the 2 is inside the radical symbol. It is the radicand. The radicand may be a number or an algebraic expression. Also, there is not limit to the number of terms the radicand may contain. It may even be infinite!
What is the number under the square root sign called?
radicand
What are similar radicals?
similar radicals are radicals with desame index and radicand ex: the square root of 5 squared
What to consider when arranging radicals?
When arranging radicals, it is important to consider the index of the radical, whether or not the radical is mixed or entire, and then the radicand.
What are 2 radicals similar?
2 radicals are similar (like terms) if, when in simplified form, the index is the same, and the radicand is the same. The coefficient may be different. EX: 3(sq root 2) and 5(sq root 2) are like terms, but 3(cube root 2) is not a like term for either.
Can the radicand be negative when the index is even?
Given that the radicand is part of the question, not part of the answer, you can make the radicand whatever you want it to be. However, in any given root sum, for example, sqrt(-4), if the index is even, such as it is in a square root sum, the answer will always be positive. If the index is odd, and the radicand is negative, the answer will also be negative.
What are the parts of radical expression?
Index, radicand, and radical :) lmfao
How do you simplify and multiply radicals?

Parts of a radical expression?
Parts include the index, the radicand, and the radical.
What are the Rules for subtracting radicals?
similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.
Any radical expression with a radicand and an even index is not a real number?
negative
Any radical expression with a negative radicand and a index is a real number?
Odd
How do you evaluate a radical?
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.
Where is the index in a radical equation?
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
