simplify 3x^{-3}

Solution

simplify

3 x^{- 3}

Solution

\frac{3}{x ^{3}}

Solution steps

3 x^{- 3}

Apply exponent rule:

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

x^{- 3} = \frac{1}{x ^{3}}

= 3 \cdot \frac{1}{x ^{3}}

Apply the fraction rule:

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

= \frac{3 \cdot 1}{x ^{3}}

Multiply the numbers:

3 \cdot 1 = 3

= \frac{3}{x ^{3}}

simplify (a^2+11a+24)/(a^3+27)simplify

\frac{a ^{2} + 11 a + 24}{a ^{3} + 27}

simplify 9/25 a^2-49/36 b^2 simplify

\frac{9}{25} a^{2} - \frac{49}{36} b^{2}

2 x^{2} - 16 x = 0

\frac{2 p}{6} - 19 = - 9
