When you multiply a positve number by a negative number what is the sign of the answer?
negative. When you multiply, if there are an odd number of negative signs, the answer is negative. If there are an even number of negative signs, the answer is positive. Or another way to think of this is that two negative signs cancel each other out when multiplying.
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.
What happens when ninth root of a number is raised to the ninth power?
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).

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.)
