simplify 2b^{-7}

Solution

simplify

2 b^{- 7}

Solution

\frac{2}{b ^{7}}

Solution steps

2 b^{- 7}

Apply exponent rule:

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

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

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

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

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

Multiply the numbers:

2 \cdot 1 = 2

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