~√2~가 소유한 ~.√.2.~ 기업(뭔가 좀 이상한데?)은 다른 안경 기업과 경쟁하려면 이 논리를 반박해야 한다. (huh?) 참고로 피파는 그 회사의 ceo다.

다음 논리를 반박하라:

a=b-(b-a)

 √a= √(b-(b-a))

 √a * √(b-(b-a)) = (b-(b-a))

 √a*√(b+(b-a)/b*b)=(b-(b-a))

 √a*√(b*(1+(b-a)/b))=(b-(b-a))

 √a*√b*√((1+(b-a)/b))=(b-(b-a))

√ab*√((1+(b-a)/b))=(b-(b-a))

√ab*√((1+(b-a)/b))=a

ab*((1+(b-a)/b))=a^2

ab*(2-a/b)=a^2

2ab-a^2=a^2

2ab=2(a^2)

ab=a^2

b=a

b=a

b=a

b=a
