When a number is raised to a negative exponent, it is equivalent to its reciprocal raised to the positive exponent. Therefore, x to the power of -7 is equal to 1 divided by x to the power of 7, or 1/x^7.

When we have x to a negative exponent we can move the x to the denominator and make the exponent positive.

So x-7 is the same as 1/x7
