Question

Which expression is equivalent to (8^2)-4 ??

Answer 1

Answer:

C

Step-by-step explanation:

Answer 2

Answer:

Option C $\frac{1}{8*8*8*8*8*8*8*8}$

Step-by-step explanation:

we have

$(8^{2})^{-4}$

Remember that

$(a)^{-b} = \frac{1}{a^{b}}$

$(a^{b})^{c}=(a)^{b*c}$

therefore

$(8^{2})^{-4}=(8)^{-4*2}=(8)^{-8}$

$(8)^{-8} = \frac{1}{8^{8}}$

$\frac{1}{8^{8}}=\frac{1}{8*8*8*8*8*8*8*8}$
