Agree

The statement "A number raised to a negative exponent is negative" is actually never true. When a number is raised to a negative exponent, it does not become negative. Instead, it becomes the reciprocal of the number raised to the positive exponent.

To understand this concept, let's consider an example:

Suppose we have the number 2 raised to the power of -3, which can be written as 2^(-3).

To evaluate this expression, we need to understand that a negative exponent represents the reciprocal of the number with a positive exponent. So, 2^(-3) is the same as 1 / (2^3).

Now, 2^3 is equal to 2 * 2 * 2, which equals 8.

Therefore, 1 / 8 is the value of 2^(-3), which is a positive fraction and not negative.
