Answer 2

Answer:

x= underoot 29 -1/2

or

x = underoot-29-1/2

explanation:

given,

underoot7+/7 + +/7 ............

let x = /7+/7+/7+/7.........

x= /7+ /x

on squaring both sides

= x^2=(/7+/x)^2

= x^2=7+x

= x^2-x=7

= x^2- x+ 1/2^2- 1/2 = 7 (cimpleting square root method)

= (x-1/2)^2= 7+ 1/2^2

= (x-1/2)^2 = 7+ 1/4

= ( x-1/2)^2 = 28+1/4

= x-1/2 = +- underoot 29/ underroot 4

= x-1/2= +- underoot 29 /2

using + sign

= x-1/2= + underoot29/2

= x= + underoot 29/2-1/2

= x= underoot 29 -1/2 ans with using + sign.

or

using - sign

x-1/2 = underoot -29/2

= x = -underoot -29 /2 -1/2

= x = underoot-29-1/2 ans with using -sign.
