Yes, it is possible to find out the value in the PHP language. You can use HTML language to display the exact format of a square + b square (a2+b2). In any programming language, you need to know about the variables. PHP variables help to save the data type’s values and you can use this variable in PHP operation. This is the mathematical formula (a2 +b2). First of all, think about the variables. There are two variables a and b in this mathematic formula (a2 +b2). In the PHP language, the variables are declared by the $ sign.
$a;
$b;
You can write the mathematic formula (a2 +b2) like this –
a*a+b*b
Use this method in PHP and get the result.
<?php
$a=2;
$b=3;
$result=($a*$a+$b*$b);
echo "(a<sup>2</sup>+b<sup>2</sup>)=".$result;
?>
It produces the output –
(a2+b2)=13
In the PHP code above, you can change the values of the variables. You need to learn PHP data types to provide any values with variables.
