Answer 2

Answer:

Hey there mate here is your answer

d) 397 x 406 = 161182

e) 48 x 53 = 2544

f) $4.1^{2}$ = 16.81

g) $81^{2} - 59^{2}$ = (81+59)(81-59) = 140 x 22 = 3080

h) $21.1^{2} - 9.9^{2}$ = (21.1 + 9.9)(21.1-9.9)= 31 x 11.2 = 347.2

i) 603 x 504 = 303912

j) 3.1 x 2.2 = 6.82

k) 107 x 98 = 10486

l) $829^{2} - 271^{2}$ = (829+271)(829-271) = 1100 x 558 = 613800
