Simplify the example using exponent rules. your answer should not include any negative exponents. 5x to the -4 power over 1x to the -9 power

is simplified to

Step-by-step explanation:

Consider the given expression "5x to the -4 power  Over  1x to the -9 power".

We can write this mathematically as,

5x to the -4 power  as

and 1x to the -9 power as
