Question

Evaluate using identities (604)^2

Answer 1

Answer:

= (600+4)^2

=(a+b)^2=a^2+2ab+b^2

a=600 b=4

= 600^2+2*600*4+4^2

Step-by-step explanation:

Answer 2

Let (600+2) (600+2) **(600=a) (2=b)

=let the formula is(a+b)^2

=then a^2+2×a×b+b^2

=600^2+2×600×2+2^2

=360000+600×4+4

=360000+2400+4

=360000+2404

=362404
