Question

if a/b= (3/7)2 ÷ (9/7)0, then find the value of (b/a)2?
pls answer fast​

Answer 1

$\\ \sf\longmapsto (3/7)2\div (9/7)0$

• Anything multiplied with 0 gives 0

$\\ \sf\longmapsto (3/7)2\div 0$

$\\ \sf\longmapsto \infty$

Now

$\\ \sf\longmapsto \dfrac{b}{a}=\dfrac{1}{\infty}=0$

$\\ \sf\longmapsto (\dfrac{b}{a})^2=0^2=0$
