Question

4. If x=
$\frac{7}{ - 9}$
Nd y=
$\frac{ - 13}{27}$
Then Verify this​

Answer 1

given:

$x = \frac{ - 7}{9}$

and

$y = \frac{ - 13}{27}$

then ,

RHS:

$|x \times y|$

$= | \frac{ - 7}{9} \times \frac{ - 13}{27} | = | \frac{91}{243} |$

LHS:

$|x| \times |y|$

$= | \frac{ - 7}{9} | \times | \frac{ - 13}{27} |$

$= \frac{91}{243}$

LHS = RHS

.hence proved
