log(根号2-1)(3log(根号2-1)(3log(根号2-1)(3因为3-2√2=(√2-1)^2所以log(√2-1)(3-2√2)=log(√2-1)(√2-1)^2=23-2根号2吧.3-

log(根号2-1)(3
log(根号2-1)(3

log(根号2-1)(3
因为3-2√2=(√2-1)^2
所以log(√2-1) (3-2√2)=log(√2-1) (√2-1)^2=2

3- 2根号2吧.
3-2根号2=(根号2-1)^2
所以,原式=log(根号2-1)[(根号2-1)^2]=2
如果是:3+2根号2=(根号2+1)^2=(根号2-1)^(-2)
那么,原式=log(根号2-1)[(根号2-1)^(-2)]=-2
