How can you find `(x-y)^(3)` without actual multiplication?
Verify with actual multiplication.

Find the multiplicative inverse of 2-3i

Find the proudct (a-b-c) (a ^(2) + b ^(2) + c ^(2) - ab + bc-ca) without actual multiplication.

Evaluate the following products without actual multiplication. (i) 101 xx 99 (ii) 999 xx999 (iii) 50 (1)/(2) xx 49 (1)/(2) (iii) 501 xx 501 (iv) 30.5 xx 29.5

Verify (i) x ^(3) + y ^(3) = (x + y) (x ^(2) -xy + y ^(2)) (ii) x ^(3) -y ^(3) = (x-y) (x ^(2) +xy +y ^(2)) using some non-zone positive integers and check by actual multiplication. Can you call these as identities ?
