Find the value of x if x=root(4)(((72*14)^(5)xx sqrt(45))/((2*8)^(3)xx sqrt(32)))

The number of real solutions of sqrt(x^(2)-4x+3)+sqrt(x^(2)-9)=sqrt(4x^(2)-14x+6)

If the direction ratios of a line are proportional to 1,-3,2 then its direction cosines are: a) (1)/(sqrt(14)),(-3)/(sqrt(14)),(2)/(sqrt(14)) b) (1)/(sqrt(14)),(3)/(sqrt(14)),(2)/(sqrt(14)) c) (-1)/(sqrt(14)),(3)/(sqrt(14)),(-2)/(sqrt(14)) d) (-1)/(sqrt(14)),(-3)/(sqrt(14)),(-2)/(sqrt(14))

The direction ratios of the line 2y+z-5=0=x-3y-6 are proportional to 3,\ 1,\ -2 b. 2,\ -4,\ 1 c. 3/(sqrt(14)),1/(sqrt(14)),(-2)/(sqrt(14)) d. 2/(sqrt(41)),(-4)/(sqrt(41)),1/(sqrt(41))

If sqrt(7)=2.646 , then find the value of (sqrt(2)+sqrt(14))^2 The following steps are involved in solving the above problem.Arrange them in sequential order. (A) 16+2sqrt(2)xxsqrt(2)xxsqrt(7) (B) 16+2xx2xsqrt(7) (C) (sqrt(2)+sqrt(14))^2=2+14+2sqrt(2)xxsqrt(14) (D) 16+4xx2.646=16+10.584=26.584

Simplify (20)/(sqrt3-sqrt(-2))+(30)/(3 sqrt(-2)-2sqrt3)-(14)/(2 sqrt3- sqrt(-2))
