Question

2. Which of the following is the number of non-perfect square numbers between the square of the numbers
n and n + 1
a) n+ 1
b) n
c) 2n
d) 2n + 1​

Answer 1

The number of non-square numbers between n² and n²+1,can be calculated by multiplying n with 2 i.e.2n

Example:-For example,to find no of non-square numbers between 6²(36) and 7²(49)(where 6 is n and 7 is n+1)

=>2n

=>2×6

=>12

Thus,there are 12 non-square numbers between 6² and 7².

Hence,the correct option is c)2n.

Answer 2

Answer:

The number of non square no. b/ w n^2 and (n+1)^2 is 2n.
