a-b is defined as 1 / ab
Polynomials cannot have negative exponent.
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100
A negative exponent of a number is the same as the reciprocal of that same number to the equivalent positive exponent.EXAMPLE : 2-3 = 1/23When multiplying powers of the same base the rule is, addthe exponents.So, if the initial exponent is negative then the number has to be multiplied by a power of that number with an equivalent positive exponent greater than the negative exponent.EXAMPLE : 2-3 x 25 = 2(-3+5) = 22 (As 5 > l3l then the resultant exponent is positive)
A negative exponent implies a reciprocal.Thus x^-a = 1/x^a or, equivalently, (1/x)^a
This is a procedure used to help people who are new to negative exponents. A negative exponent, when moved to the other side of the fraction, becomes a positive exponent and beginners are more comfortable with working with positive fractions.
The zero exponent rule basically says that any base with an exponent of zero is equal to one. For example: x^0 = 1A negative exponent is equivalent to 1 over a positive exponent.x^1 = x x^0 = 1x^-1 = 1/x
negative 4 with negative 3 as an exponent
Polynomials cannot have negative exponent.
the exponent is a negative
To change a negative exponent to a positive one, you take the reciprocal of the base raised to the positive exponent. For example, ( a^{-n} ) can be rewritten as ( \frac{1}{a^n} ), where ( a ) is the base and ( n ) is the positive exponent. This rule applies to any non-zero base.
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa

To evaluate a nonzero number with a negative integer exponent, you can use the rule that states ( a^{-n} = \frac{1}{a^n} ), where ( a ) is the nonzero number and ( n ) is the positive integer. For example, ( 2^{-3} ) can be evaluated as ( \frac{1}{2^3} = \frac{1}{8} ). This method effectively converts the negative exponent into a positive one by taking the reciprocal of the base raised to the corresponding positive exponent.
A negative exponent implies a reciprocal.Thus x^-a = 1/x^a or, equivalently, (1/x)^a

Example: (4x)-2 The answer to this would be 1/ 16x2. Multiply it out as if the negative exponent was not there ((4x)2), then that will be the denominator of the fraction. The numerator is one.
