Question

Take some time but answer correctly

Answer 1

Answer:

c

Step-by-step explanation:

Using the rule of exponents

$(a^m)^{n}$ = $a^{mn}$

note that 8 = 2³ , then

$(8)^{-3}$

= $(2^3)^{-3}$

= $2^{3(-3)}$

= $2^{-9}$ → c

Answer 2

Answer:

c) 2⁻⁹

Step-by-step explanation:

1) use negative power rule: $x^{-a} =\frac{1}{x^{a} }$

1/2⁹

2) simplify ₂⁹ to 512

1/512 ( same as (8) ⁻3
