Question

class 9th maths chp 1 find the value of -4root 81÷4root81

Answer 1

Hey friend,
Here is the answer you were looking for:
$\frac{ - 4 \sqrt{81} }{4 \sqrt{81} }$

Splitting we get,

$= \frac{ - 4 \sqrt{9 \times 9} }{4 \sqrt{9 \times 9} } \\ \\ = \frac{ - 4 \times 9}{4 \times 9} \\ \\ = - 1$

Hope this helps!!
