Question

5. Aplique as propriedades da potenciação:
a) 5⁶. 5² = b) x⁶. x⁷=
c) (-5)⁶: (-5)² = d) (+3)⁹ : (+3) =
e) [(+2)⁴ ]⁵ = f) [(-7)⁵ ]³ =

Answer 1

Resposta:

Explicação passo a passo:

$Regras...$

$a^{m}\:.\:a^{n} =a^{(m+n)}$

$a^{m}\::\:a^{n} =a^{(m-n)}$

$(a^{m}) ^{n} =a^{m\:.\:n}$

$a)$

$5^{8}$

$b)$

$x^{13}$

$c)$

$(-5)^{4}$

$d)$

$(+3)^{8}$

$e)$

$2^{20}$

$f)$

$(-7)^{15}$

Answer 2

Resposta:

$a)5^6*5^2\\\\5^{6+2}\\\\5^8$

$b)x^6*x^7\\\\x^{6+7}\\\\x^{13}$

$c)(-5)^6:(-5)^2\\\\15625:25\\\\625$

$d)(+3)^9:(+3)\\\\19683:3\\\\6561$

$e)[(+2)^4]^5\\\\2^{4*5}\\\\2^{20}$

$f)[(-7)^5]^3\\\\(-7)^{5*3}\\\\(-7)^{15}\\\\-7^{15}$
