What do you do with a fraction with a negative exponent?
So let’s say if we have 3 over 4 raised to negative 2.. If we simply flip the fraction. If we move the 3 to the bottom the 4 to the top the exponent will change sign it’s going to be positive 2..
Does negative exponent mean fraction?
Negative Exponents are Fractions
A negative exponent takes us to the inverse of the number. In other words, a-n = 1/an and 5-3 becomes 1/53 = 1/125. This is how negative exponents change the numbers to fractions. Let us take another example to see how negative exponents change to fractions.
Can a geometric series be negative?
Geometric sequences
Note that r can be positive, negative or zero. The terms in a geometric sequence with negative r will oscillate between positive and negative.
Can you have a negative exponent in the numerator?
In other words, negative exponents in the numerator can be written as positive exponents in the denominator, and negative exponents in the denominator can be written as positive exponents in the numerator.
How do you solve a fraction with a negative exponent in the denominator?
Fractions with negative exponents in the denominator can be simplified by swapping the terms with negative exponents from the denominator to the numerator and making them positive. Then, we have x − n = 1 x n and 1 x − n = x n . This means that a negative exponent is equal to the reciprocal of a positive exponent.

What do you do if the exponent is a fraction?
When the exponent is a fraction, you’re looking for a root of the base. The root corresponds to the denominator of the fraction. For example, take “125 raised to the 1/3 power,” or 125^1/3. The denominator of the fraction is 3, so you’re looking for the 3rd root (or cube root) of 125.
Can a sequence be negative?
Yes, the common difference of an arithmetic sequence can be negative.
What is the general rule of geometric sequence?
A geometric sequence is a sequence where the ratio r between successive terms is constant. The general term of a geometric sequence can be written in terms of its first term a1, common ratio r, and index n as follows: an=a1rn−1. A geometric series is the sum of the terms of a geometric sequence.

How do you find the common ratio in a geometric sequence of fractions?
Write down any two sequential terms of the geometric series, preferably the first two. For example, if your series is 3/2 + -3/4 + 3/8 + -3/16 + .. your can use 3/2 and -3/4. Divide the second term by the first term to find the common ratio.

What is an exponential function for a geometric sequence?
General Term
A geometric sequence is an exponential function. Instead of y=ax, we write an=crn where r is the common ratio and c is a constant (not the first term of the sequence, however). A recursive definition, since each term is found by multiplying the previous term by the common ratio, ak+1=ak * r.
