Question

Using algebraic formula solve the following ​

Answer 1

Answer:

The answer of your question is 7864

Step-by-step explanation:

as we know that  $(a-b)*(a+b)=a^{2}-b^{2}$

so we can take  $a=7864;b=1$

so the equation becomes

$\frac{(7864+1)(7864-1)+1}{7864}$

So according to the formula, We get

$\frac{7864^{2}-1^{2}+1 }{7864}$

So we get the answer

$\frac{7864^{2} }{7864} = 7864$
