Question

Rezolvati; (-65/4)²x 45/32

Answer 1

$\bigg(-\dfrac{65}{4} \bigg)^{2} \cdot \dfrac{45}{32} = \dfrac{65^{2}}{4^{2}} \cdot \dfrac{45}{32} = \dfrac{(5 \cdot 13)^{2}}{(2^{2})^{2}} \cdot \dfrac{3^{2} \cdot 5}{2^{5} } = \dfrac{3^{2} \cdot 5^{3} \cdot 13^{2}}{2^{9} } = \dfrac{190125}{512} = 371\dfrac{173}{512}$
