Question

एफ एक्स बाय रूट 2.25 इज इक्वल टू फाइव फाइंड द वैल्यू ऑफ एक्स​

Answer 1

Answer:

x = 7.5

x/$\sqrt{2.25}$ = 5

rationalization

x/$\sqrt{2.25}$ X $\sqrt{2.25}$/$\sqrt{2.25}$ = x$\sqrt{2.25}$ / 2.25 = 5

x$\sqrt{2.25}$= 5X2.25

x$\sqrt{2.25}$= 11.25

x = 11.25/$\sqrt{2.25}$

x = 11.25/$\sqrt{2.25}$ X $\sqrt{2.25}$/$\sqrt{2.25}$

x = 16.875/2.25

x = 7.5
