Question

Potência com expoente negativo.
$1)(6)^{ - 4} =$
$2)(4)^{ - 2} =$
$3)(7)^{ - 1} =$
$4)(10)^{ - 3}$
​

Answer 1

Oie, tudo bom?

Use:

$\boxed{a {}^{ - n} = \frac{1}{a{}^{n} }}$

1.

$6 {}^{ - 4} = \frac{1}{6 {}^{4} } = \boxed{ \frac{1}{1296} }$

2.

$4 {}^{ - 2} = \frac{1}{4 {}^{2} } = \boxed{ \frac{1}{16} }$

3.

$7 {}^{ - 1} = \boxed{ \frac{1}{7} }$

4.

$10 {}^{ - 3} = \frac{1}{10 {}^{3} } = \boxed{ \frac{1}{1000} }$

Answer 2

Explicação passo-a-passo:

1) (6)-⁴ = (1/6)⁴= 1/6•1/6•1/6•1/6= 1/1.296

2) (4)-²= (1/4)²= 1/4•1/4= 1/16

3) (7)-¹= 1/7¹= 1/7

4) (10)-³= (1/10)³= 1/10•1/10•1/10= 1/1000
