simplify 7x^{-1}

Solution

simplify

7 x^{- 1}

\frac{7}{x}

Solution steps

7 x^{- 1}

Apply exponent rule:

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

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

= 7 \cdot \frac{1}{x}

Apply the fraction rule:

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

= \frac{7 \cdot 1}{x}

Multiply the numbers:

7 \cdot 1 = 7

= \frac{7}{x}

(a + b + c + d)^{3}

4 (x + 3) + 5 (x + 2)

5 (3 t - 4) - (t^{2} + 2) - 2 t (t - 3)

(3 + 2)^{2}

csc^{3} (x) - csc^{2} (x) - csc (x) + 1
