simplify (3^{-1}+4^{-1})/(5^{-1)}

simplify

\frac{3 ^{- 1} + 4 ^{- 1}}{5 ^{- 1}}

\frac{35}{12}

Decimal Notation

2.91666 \dots

Solution steps

\frac{3 ^{- 1} + 4 ^{- 1}}{5 ^{- 1}}

Simplify

3^{- 1} + 4^{- 1} : \frac{7}{12}

= \frac{\frac{7}{12}}{5 ^{- 1}}

Apply the fraction rule:

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

= \frac{7}{12 \cdot 5 ^{- 1}}

Simplify

12 \cdot 5^{- 1} : \frac{12}{5}

= \frac{7}{\frac{12}{5}}

Apply the fraction rule:

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

= \frac{7 \cdot 5}{12}

Multiply the numbers:

7 \cdot 5 = 35

= \frac{35}{12}

2 (sin (x))^{2} + cos (2 x)

(3 - 2 i)^{10}
