Question

*If m/n = -3/4 then m²/n² = ?*​

Answer 1

Answer

(m²+n²)²

=> {(m+n)²-2mn}² [by using a²+b²=(a+b)²-2ab formula]

=> {(14)²-2×33}² [ m+n=14 and mn=33 ]

=> (196-66)²

=> (130)²

=> 16900

Answer 2

Step-by-step explanation:

$\frac{m}{n} = \frac{ - 3}{4} \\ \\ \frac{ {m}^{2} }{ {n}^{2} } = { \binom{ - 3}{4} }^{2} = \frac{9}{16}$
