प्रश्न

`(sqrt(3) + 1)/(sqrt(3) - 1)`

योग

उत्तर

`(sqrt(3) + 1)/(sqrt(3) - 1)`

= `(sqrt(3) + 1)/(sqrt(3) - 1) xx (sqrt(3) + 1)/(sqrt(3) + 1)`

= `(sqrt(3) + 1)^2/((sqrt(3))^2 - (1)^2)`

= `((sqrt(3))^2 + 2 xx sqrt(3) xx 1 + (1)^2)/(3 - 1)`

= `(3 + 2sqrt(3) + 1)/(2)`

= `(4 + 2sqrt(3))/(2)`

= 2 + `sqrt(3)`
