`{(2^(403))/(15)}=(k)/(15)` then find `k`. (a) `2` (b) `8` (c) `1` (d) `4`

If (2k-1, k) is a solution of the equation 10 x-9y=12 , then k= (a) 1 (b) 2 (c) 3 (d) 4

If (a)/(b+c)=(b)/(c+a)=(c)/(a+b)=K, then the value of K is +-(1)/(2)(b)(1)/(2) or -1(c)-1(d)(1)/(2)

If (2p+1/p)=4 , the value of (p^3+1/(8p^3)) is (a) 4 (b) 5 (c) 8 (d) 15

(17)/(15)xx(17)/(15)+(2)/(15)xx(2)/(15)-(17)/(15)xx(4)/(15) is equal to (a)0(b)1(c)10(d)11

((-1)/5)^5x\ ((-1)/2)^3 is equal to ((-1)/2)^8 (b) -\ (1/2)^8 (c) (1/4)^8 (d) (-1/2)^(15)

A A={3,6,9,12,15,18,21},B={4,6,12,16,20},C={2,4,6,8,10,12,14,16},D={15,10,15,20} , Find : (i) A - B (ii) A-C (iii) A-D (iv) B-A (v) C-A (vi) D-A (vii) B-C (viii) B-D (ix) C-B (x) D-B (xi) C-D (xii) D-C .

If the fractional part of the number (2^(403))/(15) is (k)/(15) then k is equal to

If the fractional part of the number (2^(403))/(15) is (k)/(15) , then k is equal to

If x+sqrt(15)=4, then x+(1)/(x)=2(b)4(c)8 (d) 1
