Expert Answer
1) 574
The number is of the form 5ab.
Here, a = 7 and b = 4
We will use the rule (5ab)2 = (250 + ab) x 1000 + (ab)2
Thus, (574)2 = (250 + 74) x 1000 + (74)2
= 324 x 1000 + 5476
= 324000 + 5476
= 329476
2) 541
The number is of the form 5ab.
Here, a = 4 and b = 1
We will use the rule (5ab)2 = (250 + ab) x 1000 + (ab)2
Thus, (541)2 = (250 + 41) x 1000 + (41)2
= 291 x 1000 + 1681
= 291000 + 1681
= 292681
