Question

lower perfect square of 47​

Answer 1

Now, here we have to find the lower perfect square of 47

The nearest perfect square to 47 is supposed to be 49, which is the square of 7

But 49 is greater than 47

So, the lower number that is perfect square will be 36, it is a  square of 6

Answer 2

Given number: $47$.

Here, we have to find the perfect square number, that should be less than the above given number.

Let us write the square values of consecutive natural numbers:

$1^{2} =1$

$2^{2} =4$

$3^{2} =9$

$4^{2} =16$

$5^{2} =25$

$6^{2} =36$

$7^{2} =49$

Here, number '$49$' is a perfect square. But, it is greater than given number ($47$).

So, the preceding perfect square of $49$ is '$36$' and is smaller than given number.

So, the lower perfect square of $47$ is $'36'$.
