Answer 2

Answer:

715

Step-by-step explanation:

Given: The given equation is $34^{2} -21^{2}$

To Find: We need to simplify the equation and find the value.

Concept: A square number is the number we get after multiplying a number by itself (non-fraction).To square a number just multiply the number  by itself.

Step 1:

As we can see in the question itself we need to square the given numbers first. i.e.

$34^{2} =34$×$34$               $21^{2} =21$×$21$

$34^{2} =1156$.                $21^{2} =441$.

Step 2:

Now subtract the obtained values as according to the question. i.e.

   $34^{2}-21^{2} =1156-441$

    $34^{2}-21^{2} =715$.

Hence, 715 is the answer.
