Answer 2

\(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}=\frac{\left(3^4\right)^{11}.3^{17}}{\left(3^3\right)^{10}.\left(3^2\right)^{15}}=\frac{3^{44}.3^{17}}{3^{30}.3^{30}}=\frac{3^{61}}{3^{60}}=\frac{3^1}{1}=3\)

Answer 3

\(\frac{81^{12}.3^{17}}{27^{10}.9^{15}}\)

= \(\frac{9^{13}.3^{17}}{3^{13}.9^{15}}\)

=  \(\frac{3^4}{9^2}\)

= \(\frac{81}{81}\)

= 1
