Best ResponseYou've already chosen the best response.0hmmm how would you rationalize ... say \(\bf \cfrac{1}{a^2}?\)

Best ResponseYou've already chosen the best response.1it is up to you \(\huge \frac{1^{\frac{1}{7}}}{(a^2)^\frac{1}{7}} \)

Best ResponseYou've already chosen the best response.0@nincompoop how would you work out the problem further?

Best ResponseYou've already chosen the best response.0by rationalizing, I assume you mean the exponent, as in \(\large a^{\frac{{\color{blue} n}}{{\color{red} m}}} \implies \sqrt[{\color{red} m}]{a^{\color{blue} n}} \qquad \qquad \sqrt[{\color{red} m}]{a^{\color{blue} n}}\implies a^{\frac{{\color{blue} n}}{{\color{red} m}}}\)

Best ResponseYou've already chosen the best response.1you can probably make it so there is no root in the denominator

Best ResponseYou've already chosen the best response.0the answer is supposed to be dw:1441583091798:dw

Best ResponseYou've already chosen the best response.1mathematicians decided that it is inelegant to have a root in the denominator so we are suppose to stroke their egos

Best ResponseYou've already chosen the best response.1so multiply it by 1 that mimics the denominator

Best ResponseYou've already chosen the best response.1you know how \(\huge \frac{c}{c} =1\) or any fraction that has the same numerator and denominator equals 1 with the exception of \(\large \frac{0}{0} \)

Best ResponseYou've already chosen the best response.0however can you explain why the book only put the rad over the denominator and not the numerator...this is regarding the picute i attached up there

Best ResponseYou've already chosen the best response.0why did they not put the rad sign over the 1 as well?

AngelaB97
