simplify 1/(-5/2+2)

Solution

simplify

\frac{1}{- \frac{5}{2} + 2}

- 2

Solution steps

\frac{1}{- \frac{5}{2} + 2}

Join

- \frac{5}{2} + 2 : - \frac{1}{2}

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

Apply the fraction rule:

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

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

Apply the fraction rule:

\frac{1}{\frac{b}{c}} = \frac{c}{b}

\frac{1}{\frac{1}{2}} = \frac{2}{1}

= - \frac{2}{1}

Apply rule

\frac{a}{1} = a

= - 2

\frac{12}{x ^{12}} < 0.0005

- (\frac{1}{- 3 3})^{\frac{1}{3}}

x^{2} - 16 = - x^{2} + 16

\frac{48}{4}

\frac{( - 4 x ^{5} y ^{3} z ^{7} ) ^{3} ( - 3 x ^{2} y z ^{4} ) ^{2}}{( - 2 x ^{3} y ^{4} z ^{2} ) ^{4}}
