step by step verification​

Answer 1

Answer

=10712 is the answer

Step-by-step explanation:

103×104

=(100+3)(100+4)

using identity (x+a)(x+b)=x^2 +x(a+b) +ab,

( {100})^{2} + 100(3 + 4) + 3 \times 4(100)

2

+100(3+4)+3×4

= 10000 + 700 + 12=10000+700+12

=10712 is the answer

Answer 2

Answer:

have a great day

Step-by-step explanation:

By using (x+a)(x+b)=x^2 + x(a+b) + ab , 104*103=(100+4)(100+3)=100^2 + 100(4+3) + (4*3)=10000+700+12=10712Therefore, the answer is 10712.
