Use the rules of exponents to simplify the expression below. x4n+4y5n−5x3n+2yn−2\frac { x ^ { 4 n + 4 } y ^ { 5 n - 5 } } { x ^ { 3 n + 2 } y ^ { n - 2 } }x3n+2yn2x4n+4y5n5

A) xn+2y4n−7x ^ { n + 2 } y ^ { 4 n - 7 }xn+2y4n7
B) xn+6y4n−3x ^ { n + 6 } y ^ { 4 n - 3 }xn+6y4n3
C) x7n+2y4x−3x ^ { 7 n + 2 } y ^ { 4 x - 3 }x7n+2y4x3
D) xn+2y4n−3x ^ { n + 2 } y ^ { 4 n - 3 }xn+2y4n3
E) x7n+2y4n−7x ^ { 7n+ 2 } y ^ { 4 n - 7 }x7n+2y4n7

Rules Of Exponents

Mathematical rules that govern the operations on numbers with exponents, such as multiplication and division of powers.

Expression

A mathematical phrase that can contain numbers, variables, and operation symbols but not an equality sign.

X

In mathematics, "X" is commonly used to represent an unknown quantity or variable in equations and expressions.

  • Exploit exponent properties to simplify complex expressions and solve for variables.

Final Answer :
D
Explanation :
To simplify, we can use the rule that says when dividing two powers with the same base, we can subtract the exponents. So we have: x4n+4y5n−5x3n+2yn−2=x(4n+4)−(3n+2)y(5n−5)−(n−2)=xn+2y4n−3\frac{x^{4n+4}y^{5n-5}}{x^{3n+2}y^{n-2}}=x^{(4n+4)-(3n+2)}y^{(5n-5)-(n-2)}=x^{n+2}y^{4n-3}x3n+2yn2x4n+4y5n5=x(4n+4)(3n+2)y(5n5)(n2)=xn+2y4n3 The correct choice that matches this result is D.
