If `sqrt(81)+sqrt(64)=x` ,then find the value of `x=`

If sqrt (7 sqrt (7 sqrt7 sqrt7 sqrt7)) = 7 ^(x) then find the value of x

(1) sqrt(13-x sqrt(10))=sqrt(8)+sqrt(5) then find the value of x,(2) find sqrt(7+4sqrt(3))

If x = (4sqrt15)/(sqrt5 + sqrt3) then find the value of (x + sqrt20)/(x - sqrt20) + (x + sqrt12)/( x-sqrt12)

If x = sqrt(3)- sqrt(2) find the value of x+(1)/(x)

If x=sqrt(81) , then find the value of (x^5+x^4)/(x^3)

If sqrt(x)+sqrt(441)=0.02, then the value of x is (a) 0.1764 (b) 1.764 (c) 1.64 (d) 2.64

(sqrt(x)-1)^(2)=8-sqrt(28) find the value of x

If x = (sqrt(5) + sqrt(3))/(sqrt(5) - sqrt(3)) , find the value of x^(3) + (1)/(x^(3)) .

If x = (sqrt(3) + sqrt(2))/(sqrt(3) - sqrt(2)) , find the value of x^(2) + (1)/(x^(2)) .
