Answer 1

Răspuns: $\bf \red{\bf ~\dfrac{29}{25}}$

Explicație pas cu pas:

$\bf \bigg(\dfrac{2}{5} \bigg)^0+\bigg(\dfrac{2}{5} \bigg)^{17}:\Bigg[\bigg(\dfrac{2}{5} \bigg)^3\Bigg]^5= \bigg(\dfrac{2}{5} \bigg)^0+\bigg(\dfrac{2}{5} \bigg)^{17}:\bigg(\dfrac{2}{5} \bigg)^{3\cdot5}=$

$\bf 1+\bigg(\dfrac{2}{5} \bigg)^{17}:\bigg(\dfrac{2}{5} \bigg)^{15}= 1+\bigg(\dfrac{2}{5} \bigg)^{17-15}=$

$\bf 1+\bigg(\dfrac{2}{5} \bigg)^{2}=1+\dfrac{2^2}{5^2} =\dfrac{^{25)}1~}{1}+\dfrac{4}{25}=$

$\bf \dfrac{25}{25}+\dfrac{4}{25}=\red{ \boxed{\bf ~\dfrac{29}{25}}}$
