Solution

simplify

\frac{4 ^{- 8}}{4 ^{- 4}}

Solution

\frac{1}{256}

+1

Solution steps

\frac{4 ^{- 8}}{4 ^{- 4}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= 4^{- 8 - (- 4)}

Apply rule

- (- a) = a

= 4^{- 8 + 4}

Add/Subtract the numbers:

- 8 + 4 = - 4

= 4^{- 4}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

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

4^{4} = 256

= \frac{1}{256}
