Theorem 1.3 : Let p be a prime number. If p divides a2 , then p divides a, where a is a positive integer.

An equivalence relation R in A divides it into equivalence classes A_1 ,A_2 ,A_3 What is the value of A_1 uu A_2 uu A_3 and A_1 nn A_2 nn A_3

In the figure, if B1, B2, B3,…... and A1,A2, A3,….. have been marked at equal distances. In what ratio C divides AB?

K_(a1) , K_(a2) and K_(a3) are the respective ionisation constants for the following reactions. H_(2)ShArrH^(+)+HS^(-) , HS^(-)hArrH^(+)S^(-2) H_(2)ShArr2H^(+)+S^(2-) The correct relationship between K_(a1) , K_(a2) and K_(a3) is

Let vec a=a_1 hat i+a_2 hat j+a_2 hat k , vec b=b_1 hat i+a_2 hat j+b_2 hat k ,a n d vec c=c_1 hat i+c_2 hat j+c_2 hat k , be three non-zero vectors such that vec c is a unit vector perpendicular to both vectors vec aa n d vec b . If the angle between aa n db is pi//6, then |a_1a_2a_3b_1b_2b_3c_1c_2c_3|^2 is equal to 0 1 1/4(a1 2+a2 2+a3 2)(b1 2+b2 2+b3 2) 3/4(a1 2+a2 2+a3 2)(b1 2+b2 2+b3 2)(c1 2+c2 2+c3 2)

The length of a focal chord of the parabola y2 = 4ax at a distance b from the vertex is c, then (A) b"c = 4a3 (C) 4bc = a2 15, (B) bc2 = 4a3 (D) ab = 4c3

An equivalence relation R in A divides it into equivalence classes A1,A2, A3.What is the value of A1uu A2uu A3 and A1nn A2nn A3 ?

P sold an article to Q at a profit of 20%. Q sold the same article to R at a loss of 25%. R sold the same article to T at a profit of 50%. If P bought the article at Rs 100, then at what price did T buy that article? P ने एक वस्तु Q को 20% लाभ पर बेची | Q ने यही वस्तु R को 25% हानि पर बेच दी | R ने इसी वस्तु को T को 50% लाभ पर बेचा | यदि P ने यह वस्तु 100 रुपये में खरीदी थी, तो T केलिए इस वस्तु की कीमत कया रही ?

If a_1,a_2,a_3 and a_4 be any four consecutive coefficients in the expansion of (1+x)^n , prove that a_1/(a_1+a_2)+a_3/(a_3+a_4)= (2a_2)/(a_2+a_3)

Three distinct numbers a_1 , a_2, a_3 are in increasing G.P. a_1^2 + a_2^2 + a_3^2 = 364 and a_1 + a_2 + a_3 = 26 then the value of a_10 if a_n is the n^(th) term of the given G.P. is:
