Answer:
b^6 / a
Explanation:
First, divide the coefficients (numbers) separately, which in this case is 1 since there are no numerical coefficients in the expression.Next, apply the rules of exponents to the variables (a and b):b^7 / b = b^(7-1) = b^6a^4 / a^5 = a^(4-5) = a^(-1)So, the simplified expression is:b^6 / a^1, which can be further simplified as just: b^6 / a
