Best ResponseYou've already chosen the best response.1the exponent x+1 becomes 0+1 or just 1 now do (1/2)^ 1 which is just 1/2 then do 1/2 * 4  3 or 2  3 or 1

Best ResponseYou've already chosen the best response.1x+1 becomes 2 + 1 = 1 now do (1/2)^(1) the negative exponent means you can "flip" the fraction and make the exponent positive so you get 2^1 or just 2 now do 4*23 = 83 = 5
