Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2
___
Alternatively, you can simplify the given expression:
Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 
's mutiplied together:
And then each exponent of 2 inside means you have two 
's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
