Answer 1

Answer:

2 is the only number class?

Answer 2

By taking LCM for 432 we get,

2¦ 432

2¦ 216

2¦ 108

2¦ 54

3¦ 27

3¦ 9

3¦ 3

432 = 2×2 × 2×2× 3×3 ×3

here 3 is without a pair. So 3 must be multiplied to 432 to make it as perfect square.

432 × 3 = 1296

the square root of resulting number is,

=√1296 =36
