Answer 1

$\frac{3 {}^{ - 5} \times 10 {}^{ - 5} \times 81}{3 {}^{ - 4} \times 30 {}^{ - 5} } \\ = > \frac{3 {}^{ - 5} \times 10 {}^{ - 5} \times 3 {}^{4} }{3 {}^{ - 4} \times 3 \times 10 {}^{ - 5} } \\ = > 3 {}^{ - 5} \times 10 {}^{ - 5} \times 3 {}^{4} \times 3 {}^{4} \times 3\times 10 {}^{5} \\ = > 3 {}^{4} \\ = > 81$

Answer 2

Answer:

$\frac{3 { }^{ - 5} \times 10 {}^{ - 5} \times 81}{3 {}^{ - 4} \times 30 {}^{ - 5} } = \frac{ \frac{1}{3 {}^{5} } \times \frac{1}{10 {}^{5} } \times 81 }{ \frac{1}{3 {}^{4} } \times \frac{1}{30 {}^{5} } } = \frac{3 {}^{4} \times 30 {}^{5} \times 81}{3 {}^{5} \times 10 {}^{5} } \\ \frac{3 {}^{4} \times 3 \times 10 {}^{5} \times 81 }{3 {}^{5} \times 10 {}^{5} } = 81$
