Answer 2

Answer:

1444,4225

Step-by-step explanation:

To find,

38^2 and 65^2

Recall the property,

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

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

Now,applying the property,

38^2

=(40-2)^2

=(40)^2-2(40)(2)+(2)^2

=1600-160+4

=1444

Again,applying another property,

65^2

=(60+5)^2

=(60)^2+2(60)(5)+(5)^2

=3600+600+25

=4225
