Best ResponseYou've already chosen the best response.1If I call with N the missing exponent, we can write this: \[\Large {\left( {{2^{  5}}} \right)^N} = {2^{  15}}\] and subsequently I apply the rule of power of power, so I get this condition: \[\Large  5 \cdot N =  15\] what is N?

Best ResponseYou've already chosen the best response.1We can rewrite your expression as below: \[\Large \frac{{{7^{  3}} \cdot {7^9}}}{{{7^{  8}}}} = {7^{  3}} \cdot {7^9} \cdot {7^8}\] Now I apply the rule of multiplication of power with the same basis, so I get: \[\Large \frac{{{7^{  3}} \cdot {7^9}}}{{{7^{  8}}}} = {7^{  3}} \cdot {7^9} \cdot {7^8} = {7^{  3 + 9 + 8}} = ...?\]
