It represents the order of the root that needs to be calculated.

How do you use an exponent to represent a number such as 16?

What does the denominator of a rational exponent represent?
It represents the ratio between the numerator and the denominator. It is totally misleading to suggest that it represent anything like "parts of a whole". The ratio of the surface area of a sphere to its volume is 3/r. In this expression 3 parts out of the "total" radius is not a particularly meaningful or useful concept.
As the denominator increases the fractional pieces become?
smaller
What is 13 to the exponent -6?
19
How do we change the mix number into an improper fractions?
Multiply the whole number part by the denominator of the fractional part and add the result to the numerator of the fractional part.
How do you express something in radical form?
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.
When the numerator of a fractional number is a multiple of its denominator the fractional number is equal to a?
An integer.
When is an algebraic expression considered as a non-polynomial expression?
An expression is non polynomial if it has : negative exponent fractional exponent variable exponent in the radicand

How do you make a decimal into a negative exponent?
You look at the denominator first. Then you try to find out what exponents make the denominator. After doing that, you add a negative symbol to the smaller number on the exponent.
When dividing in scientific notation what do you do with the exponents?
When dividing in scientific notation, you subtract the exponent of the divisor from the exponent of the dividend. This will give you the exponent of the quotient after division.
What is a fractional exponent?
That means that the exponent is a fraction, such as 21/2 = square root of 2, 101/3 = cubic root of 10, etc.
How do you raise a number to an exponent that is a fraction?
You carry the exponent to the numerator and denominator. If the fraction is (m/n), then (m/n)x = (mx)/(nx) For example: (3/4)2 = (32)/(42) = 9/16 If you meant that the exponent is a fraction, such as 82/3, then the denominator of the fractional exponent means to take the root (in the example, cube root) of the number, then the numerator means to take to the power (in the example, squared). You can do either operation first. 82/3 = ((8)2)1/3 = cube root(64) = 4, or ((8)1/3)2 = (2)2 = 4
What is 3m to the negative forth power?
It is the same as 1/34 . We move an exponent to the denominator and we change the exponent from positive to negative. Now 34 is 81 so the answer is 1/81 meters.If the exponent in the denominator is negative, we can move it up to the numerator and change it to a positive.
