simplify-1/7 ab-1/14 ab-1/28 ab-ab

simplify

- \frac{1}{7} ab - \frac{1}{14} ab - \frac{1}{28} ab - ab

- \frac{5}{4} ab

Solution steps

- \frac{1}{7} ab - \frac{1}{14} ab - \frac{1}{28} ab - ab

Factor out common term

ab : ab (- \frac{1}{7} - \frac{1}{14} - \frac{1}{28} - 1)

= ab (- \frac{1}{7} - \frac{1}{14} - \frac{1}{28} - 1)

- \frac{1}{7} - \frac{1}{14} - \frac{1}{28} - 1 = - \frac{5}{4}

= ab (- \frac{5}{4})

Apply rule:

a (- b) = - ab

ab (- \frac{5}{4}) = - ab \frac{5}{4}

= - ab \frac{5}{4}

= - \frac{5}{4} ab

\frac{82 + 78 + 76 + 82 + 2 x}{6} = 80

81 x^{5} - 625 x

n^{4} + 6 n^{3} + 11 n^{2} + 6 n

(\frac{π}{2})^{3}

3 (x + 1) + x = - 5
