A number with a negative index is simply the reciprocal of the same number with a positive index.
So, x-a = 1/xa
Next a number to a fractional index, (a/b) is the ath power of the bth root of the number. Equivalently, it is the bth root of the ath power of the number.
That is, xa/b = b√(xa) = (b√x)a.
Combining these results: x-a/b = 1/(xa/b) = 1/[b√(xa)]
What else can I help you with?
What do algebraic expression contains?
Constants (numbers), variables, the four basic operations of arithmetic (+, -, *, /) as well as brackets and indices (including negative and fractional ones).
Is index the same as squared?
No. The power 2, which denotes squared, is one of an infinite number of possible values for the index. Indices (or powers) can be negative, fractional, irrational or even complex.
Why are brackets needed to square negative numbers on a calculator?
It is due to the way in which a calculator does its calculations. Most calculators follow BIDMAS which stands for; brackets, indices, division, multiplication, addition and subtraction. Since indices are calculated before subtraction, the number will be squared before it is recognised as being negative.
What is negative fractional number?
A negative fractional number is a number that represents a part of a whole but has a negative value. It is expressed as a fraction where the numerator (the top part) is a negative integer, and the denominator (the bottom part) is a positive integer, such as -3/4. This indicates that the value is less than zero, showing a deficit or loss in various contexts, such as temperature or financial situations.
Do all banks have fractional routing numbers?
Yes... routing numbers are fractional and thats how a bank accounts work in the world

Why do the 5 laws of indices always work?
Because:that is how indices are defined, andif they did not always work, they would not be called laws.
How can you find the fractional form of a negative number?
The fractional form of a negative number is just like that of a positive number, except a negative sign is added in front of it. For example, -0.33333333333333... = -1/3.
What are positive and negative numbers but have no decimal or fractional portion?
Integers.
Use of negative indices in serial dilutions?
Negative indices are not used in serial dilutions. Serial dilutions involve diluting a substance by a specific factor in each step, such as 1:10 or 1:100. Negative indices are not a part of this process as they do not represent a valid dilution factor.
How does fractional disalation work?
yes
Can integers be both positive and negative?
Yes. They just can't have fractional parts.
True or False The category of numbers called integers includes negative numbers?
It is false. It does not include negative fractional numbers.

Since indices are calculated before subtraction, the number will be squared before it is recognised as being negative.
What do you call a non negative with no fractional or decimal?
They are called positive integers or whole numbers
What is negative fractional number?
A negative fractional number is a number that represents a part of a whole but has a negative value. It is expressed as a fraction where the numerator (the top part) is a negative integer, and the denominator (the bottom part) is a positive integer, such as -3/4.
