" (ii "99^(2)

Evaluate (i) (99)^2 (ii) (995)^2 (iii) (107)^2

Observe the following pattern 2^(2)-1^(2)=2+13^(2)-2^(2)=3+24^(2)-3^(2)=4+35^(2)-4^(2)=5+4 and find the value of 100^(2)-99^(2) (ii) 111^(2)-109^(2)99^(2)-96^(2)

Evaluate each of the following by using identities: (0.99)^(2) (ii) 185xx185-115xx115

Factorise 99x^(2)-202xy+99y^(2) .

Factorise 99x^(2)-202xy+99y^(2) .

Find the value of (1.99)^(2)

If two sets A and B are having 99 elements in common, then the number of elements common to each of the sets A xx B and B xx A are : a) 2 ^(99) b) 99^(2) c)100 d)18

Using suitable identity evaluate the (9.9) ^(2)
