Index, radicand, and radical :) lmfao

Odd

the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.

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.

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.

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".

Exponential fractions are basically the inverse of radicals. When you have an exponent use the denominator for the index of the radical and the numerator as the exponent to your base number. Example: 2 ^ 1/2 would be set up as the square root of 2 to the power of one. Solve the radical expression and that would be your answer.

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.

similar radicals are radicals with desame index and radicand ex: the square root of 5 squared

Using a radical (square root) bar. I can't get one on the screen, but I'm sure you know what they look like. Example: fractional exponents can be rewritten in radical form: x2/3 means the cube root of (x2) ... write a radical with an index number 3 to show cube root and the quantity x2 is inside the radical. Any fractional exponent can be done the same way. The denominator of the fractional exponent becomes the index of the radical, but the numerator stays as a whole number exponent in the radical.
