The easiest way to solve negative powers is by writing it all out.
You already know that positive powers (regular exponents) turn from something like 33 to 3 X 3 X 3 to equal 9 X 3, or 27.
Essentially, negative powers works in a very similar manner.
2-5 works out to this in expanded form: -2 X -2 X -2 X -2 X -2.
It is best to start by multiplying that expanded form in pairs. So, you group -2 X -2, and then -2 X -2, and leave the last -2 for later. -2 X -2 is a positive 4 for both results. Now, multiply both of the 4s to get 16. Now multiply that by the remaining -2 to get -32.
Tip: A shortcut method for doing this is recognizing that if the negative exponent is odd, then the answer will be multiplied just like a regular positive exponent, but the answer will be negative, and that if the negative exponent is an even number, the answer will be just like a regular positive exponent and the result will be a positive number.
Ex: 2-3 = -8 , while 3-2 = 9.

How do you solve for a negative exponent?
That depends what you want to solve. In many cases, it helps to remember the basic definition: for example, x ^ (-3) = 1 / x ^ 3. (Using the symbol "^" for powers.)

No, but dimensions can be to negative powers. For example, the dimension for frequency is [T-1].
How do you turn algebra with negative powers into fractions?
A negative powers is defined as the reciprocal of the corresponding positive power. For example, 10-3 is the same a 1 / 103.
