3 (1 + x)^{- 1}

Solution

\frac{3}{x + 1}

Solution steps

3 (1 + x)^{- 1}

Apply exponent rule:

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

= 3 \cdot \frac{1}{( x + 1 )}

Multiply fractions:

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

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

Multiply the numbers:

1 \cdot 3 = 3

= \frac{3}{1 + x}
