Answer 2

Answer:

1/21⁹*1/7⁵/1/21¹⁴

$\frac{1}{21 {}^{9 } } \times \frac{1}{7 {}^{5} } \div \frac{1}{ {21}^{14} }$

$\frac{1}{ {21}^{9} } \times \frac{1}{7{}^{5} } \times {21}^{14}$

$\frac{1}{ {21}^{9} } \times \frac{1}{7{}^{5} } \times {7}^{14} \times {3}^{14}$

$\frac{1}{ {21}^{9} } \times {7}^{9} \times {3}^{14}$

$\frac{1}{ {21}^{9} } \times {21}^{9} \times {3}^{5}$

${3}^{5}$
