Answer 2

Answer:

The odd one in the set of numbers = 19

Step-by-step explanation:

The given numbers are 1,4,9,16,19,36,49

Required to find the odd one in the given set of numbers

Solution:

Recall the concept:

Perfect square numbers are the numbers that can be expressed as the product of a number by itself

That is if P is a perfect square then we have

p = a²

If we analyze the given set of numbers all the numbers other than 19 can be written as the product of a number by itself

that is

1 = 1²

4 = 2²

9 = 3²

16 = 4²

36 = 6²

49 = 7²

Hence we can say that all the numbers except the number '19' are perfect squares.

The odd one in the set of numbers = 19
