Answer 6

To do this problem, you subtract the denominator exponent from the numerator exponent. Your denominator exponent is 5, so x-5=-2 (Im only using exponents in the equation). if you plug in 3, your exponents will be left at -2. However, this is incorrect. \[(7^3)/(7^5)=1^{-2}\]
To fix this, you add another exponent to your numerator. You will have
\[7^4/7^5=1^1\]
If you simplify one exponent from the numerator(square 7 once) you will have
\[49^3/7^5=7^{-2}\]

Answer 7

So you must plug in 4 into the numerator in order for this equation to work
