Question

Solve the following:-
$(88)^2 + (73)^2 = (?)^2 – (38)^2 – 859$

• A. 15876
• B. 15376
• C. 126
• D. 124
• E. None of these

Answer 1

Answer: (D)

124

Answer 2

Let's solve the equation step by step:

$(88)^2 + (73)^2 = (?)^2 - (38)^2 - 859$

First, calculate the squares:

$88^2 = 7744 ,73^2 = 5329, 38^2 = 1444$

Now, substitute these values back into the equation:

$7744 + 5329 = (?)^2 - 1444 - 859$

Add the values on the left side:

7744 + 5329 = 13073

Now, add 1444 and 859 on the right side:

1444 + 859 = 2303

Now, you have: $13073 = (?)^2 - 2303$

To isolate $(?)^2$, add 2303 to both sides of the equation:

$13073 + 2303 = (?)^2$

$15376 = (?)^2$

Now, take the square root of both sides:

$\sqrt{15376}$ ≈

So, the answer is approximately 124

The correct option is (D): 124
