Question

[(-3)⁴×9⁴] : [(-3)⁷:(-3)⁵×3⁹] = ?​

Answer 1

Răspuns: $\bf \red{\underline{~3~}}$

Explicație pas cu pas:

$\bf \Big[\Big(-3\Big)^4\cdot 9^4\Big] : \Big[\Big(-3\Big)^7:\Big(-3\Big)^5\cdot 3^9\Big]=$

$\bf \Big[\Big(-3\Big)^4\cdot \Big(3^2\Big)^4\Big] : \Big[\Big(-3\Big)^{7-5}\cdot 3^9\Big]=$

$\bf \Big(3^4\cdot 3^{2\cdot4}\Big) : \Big[\Big(-3\Big)^{2}\cdot 3^9\Big]=$

$\bf \Big(3^4\cdot 3^{8}\Big) : \Big(3^2\cdot 3^9\Big)=$

$\bf \Big(3^{4+8}\Big) : \Big(3^{2+9}\Big)=$

$\bf 3^{12} : 3^{11}=3^{12-11}=3^{1} =\red{\underline{3}}$
