Can a radical expression be negative?
A radical expression represents the root of a given quantity. What does it mean, then, if the value under the radical is negative, such as in √−1? There is no real value such that when multiplied by itself it results in a negative value.
When a fraction has a negative exponent?
A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3.
Can U square root 0?
Zero has one square root which is 0. √0=0. Negative numbers don’t have real square roots since a square is either positive or 0.
What happens when you square a negative number?
Yes, you can square a negative number. This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
When can you divide radicals?
When you’re multiplying radicals together, you can combine the two into one radical expression. There’s a similar rule for dividing two radical expressions. If you have one square root divided by another square root, you can combine them together with division inside one square root.
Can you divide roots?
Correct answer: When dividing square roots, we divide the numbers inside the radical. Simplify if necessary.
What are positive and negative radicals?
The ion found in any atom or group of atoms has a positive charge or a negative charge. When an electron is gained, the atoms acquire a negative charge and are called negative radicals or negative ions. When an electron is lost, the atoms acquire a positive charge and are called positive radicals or positive ions.
Does the square root of 4 equals negative 2?
√ is called the radical symbol or radix and in this example, the principal square root of 4 is 2 which is denoted by √4 = 2 because 22 = 2 • 2 = 4 and 2 are non-negative. The number underneath the radical symbol is called the radicand….Square Root From 1 to 50.
