Best ResponseYou've already chosen the best response.0\[\frac{ x^1 }{ 3 } \times \frac{ x^3 }{ 7 }\] you just multiply it.

Best ResponseYou've already chosen the best response.0Use this rule \[\LARGE x^{a} * x^{b} = x^{a+b}\] to get \[\LARGE x^{1/3} * x^{3/7} = x^{1/3+3/7} = ??\]

Best ResponseYou've already chosen the best response.0You thought the answer was x^3/21 earlier but it is x^4/21 The denominator you multiplied was correct, but your numerator was not. Now both are correct.

Best ResponseYou've already chosen the best response.0\[ x^{1/3}\times x^{3/7}=x^{1/3+3/7}=x^{7/21+9/21}=x^{(7+9)/21}\]
