Best ResponseYou've already chosen the best response.0convert 6th root to exponent \[\huge\rm \sqrt[n]{x^m} = x^\frac{ m }{ n }\]

Best ResponseYou've already chosen the best response.0nope it's 6th root so n = 6 dw:1433351042568:dw so \[\huge\rm \sqrt[6]{a^{15}} = a^\frac{ ? }{ ? } \]

Best ResponseYou've already chosen the best response.0so a 5/2 is the answer

Best ResponseYou've already chosen the best response.0not done a^5/2 \[\huge\rm a^\frac{ a \times a \times a \times a \times a }{ a \times a }\] can u cancel out 2 a's or in other words how many times 2 goes into 5 ?

Best ResponseYou've already chosen the best response.0yep right so 5/2 2 times so 45 = 1 that's mean a stay under the root and one a^2 u can write it outside the root dw:1433351567387:dw now factor 125

Best ResponseYou've already chosen the best response.0a^5/2 can be written as \[\huge\rm \sqrt{a^5} = \sqrt{a^2 \times a^2 \times a}\] (when we multiply same bases we should add their exponent ) square cancels with square root so \[a \times a \sqrt{a} = a^2 \sqrt{a}\]
