Answer 1

Given :-

$= > \frac{4 {}^{2} - 3 {}^{2} }{( \frac{1}{7}) {}^{2} }$

Solution :-

$= > \frac{16 - 9}{ \frac{1}{49} }$

$= > \frac{7}{1} \times \frac{1}{49}$

$= > \frac{7}{49}$

$= > \frac{1}{7}$

Formulas or rules :-

》 A^2 = A × A

》 If x/(y/z)

then we have to assume as 》 x/y/z/1

then it will be 》(x/y ) × (1/z)

》so at the above situation we must the assume with "1" and it will be rotated when goes to multiply with other.
