Question

Rút gọn:

\(\frac{3^{17}.81^{11}}{27^{10}.9^{15}}\)

Answer 1

3¹⁷.81¹¹/27¹⁰.9¹⁵

=3¹⁷.(3⁴)¹¹/(3³)¹⁰.(3²)¹⁵

=3¹⁷.3⁴⁴/3³⁰.3³⁰

=3⁶¹/3⁶⁰

=3

Answer 2

\(\frac{3^{17}.81^{11}}{27^{10}.9^{15}}=\frac{3^{17}.\left(3^4\right)^{11}}{\left(3^3\right)^{10}.\left(3^2\right)^{15}}=\frac{3^{17}.3^{41}}{3^{30}.3^{30}}=\frac{3^{17+41}}{3^{30+30}}=\frac{3^{58}}{3^{60}}=\frac{1}{3^2}=\frac{1}{9}\)
