` (2^(72))/(73) ` Find R.

(72)^(2) = 51 x 4 Find the value of x.

2^(73) - 2^(72) - 2^(71) is same as :

2^(73)-2^(72)-2^(71) is same as :

2^(73)-2^(72)-2^(71) is the same as:

If AxxB={(1,2),(1,3),(1,6),(7,2),(7,3),(7,6)} then find sets A and B.

cos ^ (2) (73) ^ (@) + cos ^ (2) (47) ^ (@) + cos73 ^ (@) cos47 ^ (@) =?

If projections of as line on x,y and z axes are 6,2 and 3 respectively, then directions cosines of the lines are (A) (6/2,2/7,3/7) (B) (3/5,5/7,6/7) (C) (1/7,2/7,3/7) (D) none of these

Find the remainder when 13^(73)+14^(3) is divided by 11.
