Solution

simplify

1 6^{\frac{- 7}{4}}

Solution

\frac{1}{128}

+1

Decimal Notation

0.0078125

Solution steps

1 6^{\frac{- 7}{4}}

Factor the number:

16 = 2^{4}

= (2^{4})^{\frac{- 7}{4}}

Apply exponent rule:

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

= 2^{4 \cdot \frac{- 7}{4}}

4 \cdot \frac{- 7}{4} = - 7

= 2^{- 7}

Apply exponent rule:

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

2^{- 7} = \frac{1}{2 ^{7}}

= \frac{1}{2 ^{7}}

2^{7} = 128

= \frac{1}{128}
