`(21^(2)-15^(2))^(4/3)=`

R={(2,1),(2,2),(2,3),(2,4)}

Locate the points: (2,1),(2,2),(2,3),(2,4).

Simplify: 4/9-:2/3 (ii) 3 3/7-:8/(21) 15 3/7-:1(23)/(49)

(15)/(21) of (2)/(3)-(1)/(15)=(3)/(7)

Show that {:[(4,1),(2,7)][(2,1),(3,4)] ne [(2,1),(3,4)][(4,1),(2,7)]

If |{:(4,1),(2,1):}|^(2)=|{:(3,2),(1,x):}|-|{:(x,3),(-2,1):}| , then the value of x is :

(a+1)(a+2),a+2,1(a+2)(a+3),a+3,1(a+3)(a+4),a+4,1]|=-2

Let the relation R on set A = {1,2,3,4,5} be defined as follows: R={(1,2),(2,1),(2,2),(3,3),(4,1),(2,4),(4,2),(1,5),(5,1),(5,5)} Then state which one is true in each of the following two cases

Find the value of 1-((1(2)/(3))/(3(1)/(2))+(1(1)/(6))/(3(1)/(2)))* a) (3)/(20) (b) (4)/(21)(c)(8)/(21) (d) (13)/(21)
