\(\frac{9^8\times4^3}{27^4\times6^5}\)

Answer 1

9⁸ x 4³ / 27⁴ x 6⁵

= (3²)⁸ x (2²)³ / (3³)⁴ x (3x2)⁵

= 3¹⁶ x 2⁶ / 3¹² x 3⁵ x 2⁵

= 3¹⁶ x 2⁶ / 3¹⁷ x 2⁵

= 2/3

Answer 2

\(\frac{9^8.4^3}{27^4.6^5}=\frac{\left(3^2\right)^8.\left(2^2\right)^3}{\left(3^3\right)^4.2^5.3^5}=\frac{3^{16}.2^6}{3^{12}.2^5.3^5}=\frac{3^{16}.2^6}{3^{17}.2^5}=\frac{1.2}{3.1}=\frac{2}{3}\)
