simplify (70n+10)/(5n)*4/(28n+4)

simplify

\frac{70 n + 10}{5 n} \cdot \frac{4}{28 n + 4}

\frac{2}{n}

Solution steps

\frac{70 n + 10}{5 n} \cdot \frac{4}{28 n + 4}

Cancel

\frac{70 n + 10}{5 n} : \frac{2 ( 7 n + 1 )}{n}

= \frac{2 ( 7 n + 1 )}{n} \cdot \frac{4}{28 n + 4}

Cancel

\frac{4}{28 n + 4} : \frac{1}{7 n + 1}

= \frac{2 ( 7 n + 1 )}{n} \cdot \frac{1}{7 n + 1}

Apply the fraction rule:

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

= \frac{2 ( 7 n + 1 ) \cdot 1}{n ( 7 n + 1 )}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{2 ( 7 n + 1 )}{n ( 7 n + 1 )}

Cancel the common factor:

7 n + 1

= \frac{2}{n}

7 v^{2} - 8 v - 8 = 0

- 2 + 6 x > 34

13 - 4 < 8

(3 + i)^{6}

\frac{3}{4} x^{2} = 12
