Resposta:

13) (10‐²)³×10⁴×10-⁵= 10-⁶×10⁴×10-⁵=10-⁷= resposta D

14) (-1)⁰ +(-1)⁵= 1 + (‐1 )⁵= 1 + -1 = - 1 resposta A

2 2 2 2

Answer 2

Resposta:

Olá bom dia!

Propriedades da potenciação:

$0^n = 0\\\\1^n = 1\ se \ n\ for\ par\ -1\ se\ n\ for\ impar\\\\m^{-n} = \frac{1}{m^n} \\\\m^n.m^p = m^{n+p}\\\\\frac{m^n}{m^p} = m^{n-p}\\\\(m^n)^p = m^{n.p}$

13)

$(10^2)^{-3}.10^4.10^{-5}\\\\= 10^{-6}.10^{4+(-5)}\\\\= 10^{-6}.10^{-1}\\\\=10^{-7}\\\\=\frac{1}{10^7}\\\\=0,0000007$

LETRA D.

14)

$\frac{(-1)^0}{2} + (-1)^5\\\\\frac{1}{2} - 1 = -\frac{1}{2}$

LETRA A.
