Question

Aplique a propriedade conveniente : a)(3^2)^4 b)(2.3.4)^4 c)(7^-3)^-2 d)(x.y.z)^4

Answer 1

Explicação passo-a-passo:

a)

$\sf (3^2)^4=3^{2\cdot4}$

$\sf (3^2)^4=3^8$

b)

$\sf (2\cdot3\cdot4)^4=2^4\cdot3^4\cdot4^4$

c)

$\sf (7^{-3})^{-2}=7^{(-3)\cdot(-2)}$

$\sf (7^{-3})^{-2}=7^6$

d)

$\sf (x\cdot y\cdot z)^4=x^4\cdot y^4\cdot z^4$
