`3/17 + 6/17 + (-4)/17`

If vec(DA)=veca,vec(AB)=vecb and vec(CB)=kveca where kgt0 and X,Y are the midpoint of DB and AC respectively such that |veca|=17 and |vec(XY)|=4, then k is equal to (A) 9/17 (B) 8/17 (C) 25/17 (D) 4/17

The additive inverse of 17 is -17 (b) 17 (c) 1/(17) (d) -1/(17)

If the points whose position vectors are 3i-2j-k,2i+3j-4k,-i+j+2k and 4i+5j+lambda k lie on a plane then lambda is equal to (A)-(146)/(17) (B) (146)/(17) (C) -(17)/(146) (D) (17)/(146)

17^2 . 17^5 = 17^7
