Math Problem Statement

Answer

Solve the following expression: (876 + 346)^2 + (874 - 346)^2 / (876×876 + 346×346)

Solution

The given expression is:

(876+346)2+(874346)2(876×876+346×346)\frac{(876 + 346)^2 + (874 - 346)^2}{(876 \times 876 + 346 \times 346)}

Step 1: Simplify the numerator

First term: (876+346)2(876 + 346)^2

876+346=1222876 + 346 = 1222 12222=14908841222^2 = 1490884

Second term: (874346)2(874 - 346)^2

874346=528874 - 346 = 528 5282=278784528^2 = 278784

Now, the numerator becomes: 1490884+278784=17696681490884 + 278784 = 1769668

Step 2: Simplify the denominator

876×876=767376876 \times 876 = 767376 346×346=119716346 \times 346 = 119716

Now, the denominator becomes: 767376+119716=887092767376 + 119716 = 887092

Step 3: Compute the final value

Now, divide the numerator by the denominator: 17696688870921.995\frac{1769668}{887092} \approx 1.995

This rounds to approximately 22.

Answer:

The correct answer is 2\boxed{2}.
