Question

If n is a natural number, then for how many values of n, n²+ 45 is a perfect square?

Answer 1

Answer:

Going out step-by-step

n + n = n^2 (as given in question)

Thus 2n = n^2;

Canceling out n from both the sides yields 2=n.

Thus the value of n, such that n is a natural number and if n is added to itself, t yields the same result as square of n is 2.

Answer 2

yes x =9 and n=6 I hope this will help you
