How do you rewrite a number with a negative exponent into a positive exponents?

A number with a negative exponent can be represented as so:
If you have:
2^-6
Then you could express it as:
1/2^6
In other words:
x^-y (x to the negative y power) = 1/x^y (1 over x to the y power).
This is because, for example 3^x:
3^3 = 27
3^2 = 9
3^1 = 3
So far, the numbers are being divided by three as x decreases...
3^0 = 1
Still divided by three...
3^-1 = 1/3
Now it's logical to say that you could divide this by 3 again...
Divide by three again...
3^-1 = (1/3)/3 = 1/9
As you see 3^-x = 1/3^x

How do you rewrite expressions with rational exponent as radical exponent?
In this tutorial we are going to combine two ideas that have been discussed in earlier tutorials: exponents and radicals. We will look at how to rewrite, simplify and evaluate these expressions that contain rational exponents. What it boils down to is if you have a denominator in your exponent, it is your index or root number. So, if you need to, review radicals covered in Tutorial 37: Radicals. Also, since we are working with fractional exponents and they follow the exact same rules as integer exponents, you will need to be familiar with adding, subtracting, and multiplying them. If fractions get you down you may want to go to Beginning Algebra Tutorial 3: Fractions. To review exponents, you can go to Tutorial 23: Exponents and Scientific Notation Part I andTutorial 24: Exponents and Scientific Notation Part II. Let's move onto rational exponents and roots.After completing this tutorial, you should be able to:Rewrite a rational exponent in radical notation.Simplify an expression that contains a rational exponent.Use rational exponents to simplify a radical expression.These are practice problems to help bring you to the next level. It will allow you to check and see if you have an understanding of these types of problems. Math works just like anything else, if you want to get good at it, then you need to practice it. Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument. In fact there is no such thing as too much practice.To get the most out of these, you should work the problem out on your own and then check your answer by clicking on the link for the answer/discussion for that problem. At the link you will find the answer as well as any steps that went into finding that answer.
Why is a negative divided by a negative a positive?
if we have two negative numbers, -n and -m and we divide them: (-n)/(-m) then we can rewrite the quotient as : (-1)*n/(-1)*m and... (-1)/(-1) * n/m we know that any number divided by itself is 1 by some rule: so = (-n)/(-m) = n/m which is positive
What is 3 to the negative 3 power?
You can rewrite numbers to a negative value like this: x-n=1/xn. Therefore, you can rewrite 3-3 as 1/33. Three cubed is equal to 27, so your answer is 1/27 or 0.037037

How do you perform 2x plus 2y and raise the whole thing to the negative one?
The answer to your question is (2x + 2y)^-1 = 1/(2x + 2y)^1. When you raise a number to a negative power, you can rewrite it by dividing one by the original number with the negative sign dropped from the exponent. Because the power here is 1, you can rewrite the answer again to 1/(2x + 2y) since any number raised to the power of 1 is simply the number itself. You can't add 2x and 2y because they are two different variables.
