Chapter 9: Q577 (page 1144)

Simplify : $a) \frac{u^{\frac{13}{9}}}{u^{\frac{4}{9}}} b) \frac{r^{\frac{15}{7}}}{r^{\frac{8}{7}}} c) \frac{n^{\frac{3}{5}}}{n^{\frac{8}{5}}} .$

Short Answer

Expert verified

$P a r t a) \frac{u^{\frac{13}{9}}}{u^{\frac{4}{9}}} = u P a r t b) \frac{r^{\frac{15}{7}}}{r^{\frac{8}{7}}} = r P a r t c) \frac{n^{\frac{3}{5}}}{n^{\frac{8}{5}}} = \frac{1}{n}$

Step by step solution

Part (a)Step 1:Given information

The given expression is $\frac{u^{\frac{13}{9}}}{u^{\frac{4}{9}}} .$

Part (a)Step 2:Simplification

$\frac{u^{\frac{13}{9}}}{u^{\frac{4}{9}}} = u^{\frac{13}{9} - \frac{4}{9}} = u^{\frac{13 - 4}{9}} = u H e n c e, \frac{u^{\frac{13}{9}}}{u^{\frac{4}{9}}} = u .$

Part (b)Step 1:Given information

The given expression is $\frac{r^{\frac{15}{7}}}{r^{\frac{8}{7}}} .$

Part (b)Step 2:Simplification

$\frac{r^{\frac{15}{7}}}{r^{\frac{8}{7}}} = r^{\frac{15}{7} - \frac{8}{7}} = r^{\frac{15 - 8}{7}} = r H e n c e, \frac{r^{\frac{15}{7}}}{r^{\frac{8}{7}}} = r .$

Part (c)Step 1:Given information

The given expression is $\frac{n^{\frac{3}{5}}}{n^{\frac{8}{5}}} .$

Part (c) Step 2:Simplification

$\frac{n^{\frac{3}{5}}}{n^{\frac{8}{5}}} = n^{\frac{3}{5} - \frac{8}{5}} = n^{\frac{3 - 8}{5}} = n^{- 1} = \frac{1}{n} . H e n c e, \frac{n^{\frac{3}{5}}}{n^{\frac{8}{5}}} = \frac{1}{n} .$
