Answer:
x^-6 or 1/x^6
Explanation:
Start by rewriting the problem:
x^-150 / x^-144
Since the exponents are both negative - flip the fraction and eliminate the negative signs.
x^144 / x^150
Now, we subtract the denom from the numerator leaving...
simplified to 1/ x^6 or x^-6 (either of these is correct but the first one is considered truly simplified)
The question you took in the photo is just asking what the power of x is...
so -6 is the answer.
