Question

(15) A number can be written
in the form 4m +3, for some natural number m. Can this number be a perfect
square?​

Answer 1

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.
