Best ResponseYou've already chosen the best response.1i have used law od indices \(2^{1/2}.2^{1/2}= 2^{1/2+1/2}=2^1=2\)

Best ResponseYou've already chosen the best response.1\[(2^{1/2}  2^{1/2})^2 = (2^{1/2}2^{1/2})(2^{1/2}2^{1/2})=\]\[2^{1/2}*2^{1/2}2^{1/2}2^{1/2}  2^{1/2}2^{1/2} + 2^{1/2}2^{1/2} = \]\[2^12^02^0+2^{1} = 2  1  1 + \frac{1}{2} = \frac{1}{2}\]

Best ResponseYou've already chosen the best response.1Maybe easier to write \(a = 2^{1/2}\) and \(b = a^{1/2}\) then \[(ab)^2 = a^2  2ab + b^2 = (2^{1/2})^{1/2}  2*2^{1/2}*2^{1/2} + (2^{1/2})^2 =\]\[2^1  2*2^0 + 2^{1} = 2^{1} = \frac{1}{2}\] and use some different properties :)
