Answer:
The value of the expression 5² x 8² + 7.4² - 2 x 5 x 8 x 7.4 is approximately 1062.76.
Explanation:
To evaluate the expression 5² x 8² + 7.4² - 2 x 5 x 8 x 7.4, let’s calculate each term step by step:
5² = 5 x 5 = 25
8² = 8 x 8 = 64
7.4² = 7.4 x 7.4 = 54.76
2 x 5 x 8 x 7.4 = 592

Now, let’s substitute these values back into the original expression:
25 x 64 + 54.76 - 592
= 1600 + 54.76 - 592
= 1654.76 - 592
= 1062.76
