negative 4 with negative 3 as an exponent
Polynomials cannot have negative exponent.
the exponent is a negative
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100
A negative exponent implies a reciprocal.Thus x^-a = 1/x^a or, equivalently, (1/x)^a
A fraction
Negative x negative x negative = negative.
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.
If you have a negative exponent, then put 1/the number multiplied by itself the number of times of the exponent. For example: 3-2=1/(3x3)=1/9
negative 8 would be the base and the 15 would be the exponent
