Answer 1

Answer:

(150)^2

(100+50)^2

= (100)^2 + (50)^2 + 2×100×50

= 10000 + 2500 + 10000

= 22500

Step-by-step explanation:

Using Identity

(a+b)^2

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

Answer 2

Answer:(149-1)2= (A2-2AB+B2)identity

=(149)2 -2(149)(1)+(1)2

=(22,201)-(298)+1

=22,201-298+1

=22,201-297

= 21904 ans
