Answer: 7
Explanation:
To do this, we need to simplify the numerator.
This means we need to multiply 7^8 x 7^3 x 7^4
To multiply these, we add the exponents together.
This gives us 7^15.
Now, we need to simplify the denominator.
This means we need to multiply 7^9 x 7^5
This gives us 7^14.
Now that we have both the numerator and denominator simplified, we divide 7^15 and 7^14.
To divide 7^15 and 7^14, we need to subtract the exponents.
This gives us 7^1.
7^1 = 7.
