Answer 1

6.

I. a= 3 , b=4

5×(a+b)= 5×(3+4)= 5×7= 7

(a+b)×7= (3+4)×7= 7×7= 49

(a+b)×(a+b)= (3+4)×(3+4)= 7×7= 49

II. a=5 , b=5

5×(a+b)= 5×(5+5)= 5×10= 50

(a+b)×7= (5+5)×7= 10×7= 70

(a+b)×(a+b)= (5+5)×(5+5)= 10×10= 100

III. a=6 , b=3

5×(a+b)= 5×(6+3)= 5×9= 45

(a+b)×7= (6+3)×7= 9×7 = 63

(a+b)×(a+b)= (6+3)×(6+3)= 9×9= 81
