Question

SIMPLIFIQUE:
a- ( x³+¹ * x² *x³)² / (x³+¹)³+² =
b- (y³+² *y³*y²)³ / (y¹¹)²+² =

Answer 1

.
$(x^4.x^2.x^3)^2\div(x^4)^5= \\ \\ (x^{4+2+3})^2\div x^{20}= \\ \\ (x^9)^2\div x^{20}= \\ \\ x^{18}\div x^{20}= \\ \\ x^{18-20}=x^{-2}$

b)
$(y^5.y^3.y^2)^3\div (y^{11})^4= \\ \\ (y^{5+3+2})^3\div y^{44}= \\ \\ (y^{10})^3\div y^{44}= \\ \\ y^{30}\div y^{44}= \\ \\ y^{30-44}=y^{-14}$
