Find the value of `5.overline 2`

Find the sum of 3.overline2 and 5.overline4 .

The value of A. overline A in Boolean algebra is.

In the given figure overline(DE)||overline(AC) . Find the value of x. (a) 1 (b) 2 (c) 3 (d) 4

The value of overline(23) + 0. overline(22) is

The value of overline A + A in the Boolean algebra is

If overline(c)=2overline(a)+5overline(b), |overline(a)|=a, |overline(b)|=b and the angle between overline(a) and overline(b) is (pi)/(3) , then c^(2) =

If overline(a) is perpendicular to overline(b) and overline(c), |overline(a)|=2, |overline(b)=3, |overline(c)|=4 and the angle between overline(b) and overline(c) is (2pi)/(3) , then |[[overline(a), overline(b), overline(c)]]|=
