Escribe dos estrofas para dos poemas usando en cada una la acepción de una palabra polisénica. Observa el ejemplo.

a) 15 de \( \frac{1}{3}=5 \) b) 24 D \( \frac{2}{6}=8 \) c) \( 32 d t \frac{3}{6}=12 \) d) \( 21 d \in \frac{4}{1}=12 \) RESolve IAS siguiEN \( a=\frac{180}{4 \sqrt{45}}+\frac{30}{45}= \)

Factor out the greatest common factor. If the greatest common factor is 1 , just retype the polynomial. \[ 26 h^{10} j^{4}-39 h^{10} j^{3}+13 h^{10} j^{2} \]

Exercice 2: (1) Montrer les implications suivantes: a \( (\forall \mathrm{x}, \mathrm{y} \in \mathbb{R}) ; \quad \mathrm{Si} \quad(|\mathrm{x}| \leq 1 \) et \( |\mathrm{y}| \leq 1) \quad \) alors \( \sqrt{1-\mathrm{x}^{2}}+\sqrt{1-\mathrm{y}^{2}} \leq 2 \sqrt{1-\left(\frac{\mathrm{x}+\mathrm{y}}{2}\right)^{2}} \) b \( \left(\forall \mathrm{x}, \mathrm{y} \in \mathbb{R}^{*}\right) ; \quad 2 \mathrm{x}+4 \mathrm{y}=1 \Rightarrow \frac{1}{\mathrm{x}^{2}+\mathrm{y}^{2}} \leq 20 \) (2) En utilisant "Le raisonnement par les équivalences successives", montrer que: a \( \left(\forall \mathrm{x}, \mathrm{y} \in \mathbb{R}^{+}\right) ; \quad \mathrm{x} \sqrt{\mathrm{x}^{2}+1}=\mathrm{y} \sqrt{\mathrm{y}^{2}+1} \Longleftrightarrow \mathrm{x}=\mathrm{y} \) b \( \left(\forall \mathrm{x}, \mathrm{y} \in \mathbb{R}_{+}^{*}\right) ; \quad \mathrm{x} \prec \mathrm{y} \Longleftrightarrow \frac{\mathrm{x}}{\mathrm{y}} \prec \frac{2 \mathrm{x}+5 \mathrm{y}}{5 \mathrm{x}+2 \mathrm{y}} \prec \frac{\mathrm{y}}{\mathrm{x}} \)
