+1

Decimal Notation

0.00390625

Solution steps

6 4^{\frac{- 4}{3}}

Factor the number:

64 = 4^{3}

= (4^{3})^{\frac{- 4}{3}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}, a \geq 0

= 4^{3 \cdot \frac{- 4}{3}}

3 \cdot \frac{- 4}{3} = - 4

= 4^{- 4}

Apply exponent rule:

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

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

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

4^{4} = 256

= \frac{1}{256}
