Question

If 27^x = 81^y Then, x:y = ??

Answer 1

Answer:

Step-by-step explanation:

27^x=81^y

3^3x =3^4y

[3×3×3=27;3×3×3×3=81]

Therefore x:y

                =3:4

$(27) {}^{x} = (81) {}^{y} \\ = > ( {3}^{3} ) {}^{x} = ( {3}^{4} ) {}^{y} \\ = > {3}^{3x} = {3}^{4y} \\ = > 3x = 4y \\ = > \frac{x}{y} = \frac{3}{4}$
