Question

rationalizati si aduceți lanforma ireductubila 45/radical din 75​

Answer 1

Răspuns:

Explicație pas cu pas:

$\displaystyle{ \frac{45}{\sqrt{75}} = \frac{45\sqrt{75}}{75}^{(15} = \frac{3\sqrt{75}}{5} }$

$\displaystyle{ \sqrt{75} = 5\sqrt{3} \rightarrow \frac{3\sqrt{75}}{5} = \frac{3 \cdot \not 5\sqrt{3}}{\not 5} }$

$\boxed{=3\sqrt{3}}$
