Repede va rogg

Answer 1

Răspuns:

• 9

Explicație pas cu pas:

(2^3)^7 : 4^9 + 3^0 =

2^(3x7) : (2^2)^9  + 1 =

2^21 : 2^(2x9) + 1 =

2^21 : 2^18  +  1 =

2^(21-18) + 1 =

2^3 + 1 =

8 + 1 =

9

Answer 2

Răspuns: $\bf \red{\underline{9}}$

Explicație pas cu pas:

$\bf \big(2^3\big)^7:4^9+3^0=$

$\bf 2^{3\cdot7}:\big(2^2\big)^9+3^0=$

$\bf 2^{21}:2^{2\cdot9}+1=$

$\bf 2^{21}:2^{18}+1=$

$\bf 2^{21-18}+1=2^{3}+1=$

$\bf 8+1=\red{\underline{9}}$

$\green{\bf \underline{Formule~pentru~puteri}:}$

$\bf a^{0} = 1;$

$\bf (a^{n})^{m} = a^{n \cdot m};$

$\bf a^{n}\cdot a^{m} =a^{n+m};$

$\bf a^{n}: a^{m} =a^{n-m}$
