The expression 12x^-4 can be rewritten as 12 divided by x^4.
When a variable is raised to a negative exponent, it means that the variable is in the denominator of the fraction. In this case, x^-4 is equivalent to 1/x^4. Therefore, 12x^-4 is equivalent to 12 divided by x^4.
For example, if we substitute a value for x, such as x = 2, the expression would be 12/(2^4) = 12/16 = 3/4.
In summary, the expression 12x^-4 is equivalent to 12 divided by x^4.
