Best ResponseYou've already chosen the best response.3when we multiply same bases we should `add` exponents \[\huge\rm x^m \times x^n=x^{m+n}\] and when we divide same base , `subtract` their exponents \[\huge\rm \frac{ x^m }{ x^n }=x^{mn}\]

Best ResponseYou've already chosen the best response.3don't guess it's easy when multiply same bases we should `add` their exponents so \[7^{3} \times 7^{9}=\rm what ?\]

Best ResponseYou've already chosen the best response.3here is an example \[\huge\rm 2^2 \times 2^3 = 2^{2+3} = 2^5\] base would stay the same \[\large\rm 7^{3} \times 7^9=7^{3+9}=7^?\]

Best ResponseYou've already chosen the best response.3i said just `add` exponents 3 and 9 are exponents 93= ??

Best ResponseYou've already chosen the best response.3yes right so numerator would be 7^6 \[\huge\rm \frac{ 7^6 }{ 7^{8} }\] 2nd exponent rule when we divide same base we should `subtract` their exponents here is an example \[\huge\rm \frac{ 2^4 }{ 2^{3} }=2^{4(3)}\]

Best ResponseYou've already chosen the best response.3we would bec 2nd exponent is negative that would makes addition

Best ResponseYou've already chosen the best response.3here is an example \[\huge\rm \frac{ 2^4 }{ 2^{3} }=2^{4(3)}=2^{4+3}=2^7\] basically we are subtracting 4 from 3 4(3) but bec 3 is negative that would makes positive 3

Best ResponseYou've already chosen the best response.3what about 4^2 ? \[\huge\rm \frac{ 7^6 }{ 7^{8} } = ?\]

Best ResponseYou've already chosen the best response.3look at the example then solve this \[\huge\rm \frac{ 7^6 }{ 7^{8} } = ?\]

Best ResponseYou've already chosen the best response.3you never said that anyways that's an example now solve ur question which is \[\huge\rm \frac{ 7^6 }{ 7^{8} } = ?\]

Best ResponseYou've already chosen the best response.3move the exponent from denominator to top when you do that sign of the denominator exponent would change
