Answer:
To rewrite the expression y^m*n/y^m+n using the quotient rule, we can apply the rule which states that when dividing two exponential expressions with the same base, we subtract the exponents.
Using the quotient rule, the expression can be rewritten as:
y^(m*n - (m+n))
Simplifying the exponent, we have:
y^(mn - m - n)
Therefore, the expression y^m*n/y^m+n can be rewritten as y^(mn - m - n) using the quotient rule.
