easy one............

Answer 2

The value of blank would be 97.

Step-by-step explanation:

Since we have given that

$(16)^2 + (21)^2 - (13)^2 + ? = (25)^2$

So, it becomes,

$16^2=256\\\\21^2=441\\\\13^2=169\\\\25^2=625$

Now, it becomes,

$256+441-169+x=625\\\\528+x=625\\\\x=97$

Hence, the value of blank would be 97.
