Express in exponential form​

Answer 1

Answer:

THIS IS THE ANSWER.........

Answer 2

$\: \: \: \: \frac{ {9}^{6} \times {7}^{4} }{ {3}^{8} \times 21 } \\ = \: \frac{ {( {3}^{2}) }^{6} \times {7}^{4} }{ {3}^{8} \times {3}^{1} \times 7 } \: \: \: \: \: \: \: \: \: \: \: \: ... \: ( { {a}^{m} )}^{n} = {a}^{mn} \\ = \frac{ {3}^{12} \times {7}^{4} }{ {3}^{9} \times {7}^{1} } \: \: \: \: \: \: \: \: \: \: ... \: ( {a}^{m} \times {a}^{n} = {a}^{m + n} ) \\ = {3}^{12 - 9} \times {7}^{4 - 1} \: \: \: ... \: ( \frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n} ) \\ = {3}^{3} \times {7}^{3} \\ = {(3 \times 7)}^{3} \: \: \: ... \: ( {a}^{m} {b}^{m} = {(ab)}^{m} ) \\ = {21}^{3}$

Hence, the exponential form of the given expression is 21³.
