Question

[(-27)³]⁴ : [(-3)³ · (-9)³] : [(-81)³]⁰:3²³
dau coroană ​

Answer 1

Explicație pas cu pas:

[(-27)³]⁴:[(-3)³×(-9)³]:[(-81)³]⁰:3²³=

(-27)¹²:27³:(-81)⁰:3²³=

27⁹:1:3²³=

27⁹:3²³=

(3³)⁹:3²³=3²⁷:3²³=3⁴=81

Succes!

Answer 2

Răspuns: $\bf \red{ \underline{{3}^{4}=81}}$

Explicație pas cu pas:

$\bf \Big[ \big( - 27 \big)^{3} \Big]^{4} : \Big[ \big( - 3\big)^{3} \cdot \big(- 9 \big)^{3} \Big]:\Big[ \big( - 81 \big)^{3} \Big]^{0} : {3}^{23} =$

$\bf \Big[ \big( - {3}^{3} \big)^{3} \Big]^{4} : \Big[ \big( - 3\big)^{3} \cdot \big(- {3}^{2} \big)^{3} \Big]:\Big[ \big( - {3}^{4} \big)^{3} \Big]^{0} : {3}^{23} =$

$\bf \Big( - {3}^{3 \cdot3} \Big)^{4} : \Big[ \big( - 3\big)^{3} \cdot \big(- 3^{2 \cdot3} \big) \Big]:\Big( -3^{4 \cdot3} \Big)^{0} : {3}^{23} =$

$\bf \Big( - {3}^{9} \Big)^{4} : \Big[ \big( - 3\big)^{3} \cdot \big(- 3^{6} \big) \Big]:\Big( -3^{12} \Big)^{0} : 3^{23} =$

$\bf {3}^{9 \cdot4} : \Big( 3^{3 + 6} \Big):\Big( -3^{12} \Big)^{0} : 3^{23} =$

$\bf {3}^{36} : \big( 3^{9} \big):1 : 3^{23} =$

$\bf {3}^{36} : 3^{9} : 3^{23} = {3}^{36 - 9 - 23} =$

$\bf \red{ \underline{{3}^{4}=81}}$
