simplify 3b^{-2}

Solution

simplify

3 b^{- 2}

\frac{3}{b ^{2}}

Solution steps

3 b^{- 2}

Apply exponent rule:

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

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

= 3 \cdot \frac{1}{b ^{2}}

Apply the fraction rule:

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

= \frac{3 \cdot 1}{b ^{2}}

Multiply the numbers:

3 \cdot 1 = 3

= \frac{3}{b ^{2}}

2^{3} \cdot 2^{- 6}

tan (x) + tan (x)

18 + \frac{3}{5} (6 x - 15)

(6^{- 2})^{- 2}

310 + 1010
