`[(1+1/(10+1/10))(1+1/(10+1/10))-(1-1/(10+1/10))(1-1/(10+1/10))]-:[(1+1/(10+1/10))+(1-1/(10+1/10))]` का सरलीकृत मान है?

[(1+(1)/(10+(1)/(10)))xx(1+(1)/(10+(1)/(10)))-(1-(1)/(10+(1)/(10)))xx (1-(1)/(10+(1)/(10)))+(1+(1)/(10+(1)/(10)))+(1-(1)/(10+(1)/(10)))] simplifies to

1. (1)/(10)+(3)/(10)+(6)/(10)

[(1+(1)/(10+(1)/(10)))(1+(1)/(10+(1)/(10)))-(1-(1)/(10+(1)/(10)))(1-(1)/(10+(1)/(10)))] simplifies to (20)/(101) (b) (90)/(101) (c) (100)/(101) (d) (101)/(100)

1/4+2/4 3/10+2/10+1/10

(10)^2 - 2(10) (1)+(1)^2 = __

((1)/(1.4 )+ (1)/(4.7 ) +(1)/(7.10 )+(1)/(10.13 )+(1)/(13.16)) is equal to

10 div 10 xx 10 + 10 - 1

If x+ (1)/(x)= -1 find x^(10) + (1)/(x^(10)) =?
