Best ResponseYou've already chosen the best response.0to get rid of the square, you must square root both sides

Best ResponseYou've already chosen the best response.0no what you do first is you hvae to square root both sides . only then you can add 5 to both sides. so t  5 =  or + sqrt(81) so t  5 = + or negative 9 so t  5 = 9 and therefore t = 14 and t  5 = 9 and therefore t = 4 so t = 14 and 4 are both valid answers

Best ResponseYou've already chosen the best response.0I see how you got it now I guess with similar problems I thought I did the same thing to this one too. How would I do one with 1/2(x1)^5=16

Best ResponseYou've already chosen the best response.0first multiply by the reciprocal of 1/2 on both sides so you have grouping symbol by itself on one of the equation then you will have (x1)^5=2*16

Best ResponseYou've already chosen the best response.0now since this is raised to the 5th power with take the 5th power of both sides giving us x5=32^(1/5)

Best ResponseYou've already chosen the best response.0since 32^(1/5)=[2*2*2*2*2]^(1/5)=2

Best ResponseYou've already chosen the best response.0z^2=48/3=16 so z=plus or minus 4
