Question

Aplique a propriedade da potência: a) [(-4)² ]³ = b) [(+5)³ ]⁴ = c) [(-3)³ ]² = d) [(-7)³ ]³ = e) [(+2)⁴ ]⁵ = f) [(-7)⁵ ]³ =

Answer 1

Resposta:

a) [ ( - 4 ) ² ] ³ =  

( - 4 ) ² * ³   ( multiplica - se os expoentes )

( - 4 ) ^ 6

4 ^ 6 = 4096  

b)  [(+5)³ ]⁴ =

$5^{12}=\\244140625$

c)

$[(-3)^3]^2 =\\(-3)^6=\\729$

d)

$[(-7)^3 ]^3=\\(-7)^9=\\-7^9 = - 40353607$

e)

$[(+2)^4 ]^5=\\2^{20}=1048576$

f)

$[(-7)^5 ]^3=\\(-7)^{15}=\\- 4747561509943$
