1.	(15) A number can be writtenin the form 4m +3, for some natural number m. Can this number be a perfect square?
Answer» Step-by-step explanation: no as we know m2 is perfect square such m2 = 4m + 3 0 = m2 - 4m - 3 DISCRIMINANT = 16 ___ 4 * 1 * -3 16 > -12 discriminant not EQUAL to 0. so it is not a perfect square.

Answer»

Step-by-step explanation:

no as we know m2 is perfect square

such m2 = 4m + 3

0 = m2 - 4m - 3

16 ___ 4 * 1 * -3

16 > -12

discriminant not EQUAL to 0.

so it is not a perfect square.
