QUESTION :-

3. Find the squares of the following numbers usingthe identity (a + b)2 = 0? + 2ab + b.(a) 610 (b) 102 (c) 305

SOLUTION:-

FIND IT:-

the identity (a + b)2 = 0? + 2ab + b.

we have

(a) 610

(b) 102

(c) 305

then putting the value in the hints

(a + b)2 = 0? + 2ab + b.

putting the value

(610+102)2=0×305?+2×610×102+102

(712)2=124440+102

1424 =124542

= 124542-1424

=123118
