Tuesday, August 31, 2010

Lets see multiplication and dividing radicals, a very simple concept of mathematics.

1. Multiplying the two radicals: √14 and √9

( $\displaystyle\sqrt{{{14}}}$ ) ( $\displaystyle\sqrt{{{9}}}$ ) = $\displaystyle\sqrt{{{14}}}$ $\displaystyle\sqrt{{{7}}}$

= $\displaystyle! \sqrt{{{7}\cdot{2}\cdot{9}}}$

= 3 $\displaystyle\sqrt{{{14}}}$

= 3 $\displaystyle\sqrt{{{14}}}$

Answer: 3 $\displaystyle\sqrt{{{14}}}$

2. Dividing the given radicals: 9 $\displaystyle\sqrt{{25}}$ / 45

9 $\displaystyle\sqrt{{25}}$ / 45 = (9 × 5) / 45

= 45 / 45

! = 1

Answer: 1

dividing radicals has example index 2. So that we can able to divide directly.
