Best ResponseYou've already chosen the best response.0the expression \[\sqrt[4]{16x ^{2}y ^{7}?}\] is equivalent to which? 2x^(1/2)y^(7/4) , 4x^(1/2)y^(7/4), 2x^8y^28, or 4x^8y^28.

Best ResponseYou've already chosen the best response.1Use the the fundamental rule with radicals that (ab)^(1/2) = (a)^(1/2) * (b)^(1/2)

Best ResponseYou've already chosen the best response.1Do you understand radicals? They are simply used to determine what two (or 4 in this case) identical numbers multiply together to give what is under the radical for example 3^(2) = 9 3*3 = 9 (9)^(1/2) =3

Best ResponseYou've already chosen the best response.1so split up the terms of your problem into (16)^(1/4) * (x^(2))^(1/4) * (y^(7))^(1/4) I will solve the first term to show you how to solve this so we have (16)^(1/4) if you raise 2^(4) you realize you can get 16 so it simplifies to just 2 so now you are left with 2 * (x^(2))^(1/4) * (y^(7))^(1/4) Now to solve a variable what times what give y^(7) that will allow it to be simplified (when multiplying numbers with exponents we add the exponents). so we have 2 * (x^(2))^(1/4) * (y^(4))^(1/4) * (y^(3))^(1/4)

Best ResponseYou've already chosen the best response.1remember the rule that (x^(4))^(1/4) is the same as x^((x/1)(1/4)) = x^(1) = x

Best ResponseYou've already chosen the best response.1wait apply the rule I just showed you so (x^(2))^(1/4) = x^((2/1)(1/4))

Best ResponseYou've already chosen the best response.1y^(7/4) can be simplified more you would know that if you read what I posted
