If a =`6+2sqrt3` find `a-1/a`

if a = 2 - sqrt3 find (a - 1/a)^3

If x= 2sqrt(3)+2sqrt(2) find : (1)/(x)

If a = sqrt3, b = (1)/(2) (sqrt6 + sqrt2), and c = sqrt2 , then find angle A

If 3a+(1)/(3a) = 2sqrt3 , evaluate: 3a- (1)/(3a)

In DeltaABC, a=2, b=sqrt(6) and c=sqrt(3)+1 , find angleA .

If a=(1+i)/sqrt(2) find the value of a^6+a^4+a^2+1

If sqrt(2)=1. 414 , and sqrt(3)=1.732 find the value of sqrt(3)+sqrt(6) upto three place of decimals.

If the sides of a triangle are proportional to 2,\ sqrt(6)\ a n d\ sqrt(3)-1, find the measure of its greatest angle.

If sqrt(3) = 1.73 find the value of : (2+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))+(sqrt(3)-1)/(sqrt(3)+1)-(sqrt(3)+1)/(sqrt(3)-1) .

If sqrt(2)= 1.4 and sqrt(3) = 1.7 find the value of each of the correct to one decimal place: (2-sqrt(3))/(sqrt(3))
