Answer 2

Answer:

At least 72 must be subtracted from 6156 to make it a perfect square ​

Step-by-step explanation:

First we have to find the square root of 6156:

$\sqrt{6156}$=2×3×3× $\sqrt{19}$  

=18×4.358=78.444...

Now, we find the square of 78 as follows:

$78 ^2=78 \cdot 78=6084$

Let us now subtract 6156 from 6084 as shown below:

  $6156-6084=72$

Hence, 72 will be subtracted from 6156 to make it a perfect square.
