Question

I need the answer please. Because I think i got mine wrong

Answer 1

Answer:

a.  1 / 8^2    b. 3^3    c 1 / 6^4.

Step-by-step explanation:

We used the following rules   x^-n = 1/x^n,  

1 / x^-n = x^n

and  x^n * x^m = x^(n+m).

Answer 2

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

• $a^{-m}$ ⇔ $\frac{1}{a^{m} }$

• $a^{0}$ = 1

• $a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

(a)

$8^{-2}$ = $\frac{1}{8^{2} }$

(b)

$\frac{1}{3^{-3} }$ = 3³

(c)

$6^{-12}$ × $6^{8}$ × $6^{0}$

= $6^{(-12+8)}$ × 1

= $6^{-4}$

= $\frac{1}{6^{4} }$
