What is the radical expression of a number indicating which root is meant?
A radical expression represents the root of a number and is indicated by the radical symbol (√). The index of the radical, typically written as a small number to the upper left of the radical symbol, specifies which root is meant; for example, √x denotes the square root, while ∛x denotes the cube root. If the index is omitted, as in √x, it is generally assumed to be 2, indicating a square root.
How is a radical equation similar to a linear equation?
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
Why cant you evaluate the square root of negative twenty five using real numbers?
using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number
What is the number or expression inside a radical?
A square root
What are the differences between a and a square roots?
a is a real number since we use just letters to represent real numbers. if a > 0, then its square root is also a real number, so it has two square roots, one positive and one negative. Be careful when you use the radical sign, because it is looking only for the principal square root of a, which is the positive one. if a < 0, then its square root is an imaginary number.
Why can't you factor negative radical numbers?
You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
What is the symbol used to represent the nonnegative square root of a number?
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.

When you square a number the number is positive?
When you square a real number the answer is positive,
Change a mixed radical to an entire radical?
you have to square the outside number and then multiply it by the number inside the squareroot sign.
How can you tell the value of a radical is a rational number?
If the number inside the radical is a perfect square or a ratio of perfect squares.
What are the square roots in radical form?
it the number that is simfilied
