No.

Radical(1.21) = 1.1, for example, is rational.

-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 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!

The radical symbol ( âˆš ) followed by a line above what's in the radical, designates positive square root.

It is the RADICAL SIGN , its definition is - the symbol used to indicate a nonnegitive square root.

If the symbol preceding the 61 is intended to be a radical sign, the answer is yes. If it is not a radical, it depends on the value of v.

There is no special symbol to indicate an irrational number.

There is no special symbol for an irrational number. However, it is known that many square roots, cubic roots, etc., as well as some special numbers such as pi and e, are irrational.

NO !!! However, the square root of '5' is irrational 5^(1/2) = 2.236067978... Casually an IRRATIONAL NUMBER is one where the decimals go to infinity and there is no regular order in the decimal numbers. pi = 3.141592.... It the most well known irrational number. However, 3.3333.... Is NOT irrational because there is a regular order in the decimals. Here is a definitive statement of irrational numbers. Irrational numbers are real numbers that cannot be represented as simple fractions. An irrational number cannot be expressed as a ratio, such as p/q, where p and q are integers, qโ 0. It is a contradiction of rational numbers. Irrational numbers are usually expressed as R\Q, where the backward slash symbol denotes โset minusโ. It can also be expressed as R โ Q, which states the difference between a set of real numbers and a set of rational numbers.

An irrational number is a number that cannot be represented by a ratio of two integers, in the form x/y where y > 0. There is no particular symbol for irrational numbers. The set notation Râˆ© Q', representing Reals (R) other than Rationals (Q) may be used.

The function of a radical in math is to indicate the operation of taking the root of a number. It is represented by placing a radical symbol (โ) before the number. The number inside the radical is known as the radicand.
