Calculate the value of 7² - 5².

Explanation:
To find the value of \(7^2 - 5^2\), we start by calculating each square. First, calculate \(7^2\): \[ 7^2 = 7 \times 7 = 49 \] Next, calculate \(5^2\): \[ 5^2 = 5 \times 5 = 25 \] Now, subtract \(5^2\) from \(7^2\): \[ 7^2 - 5^2 = 49 - 25 = 24 \] So, the result of \(7^2 - 5^2\) is \(24\). This value is obtained through straightforward arithmetic, exhibiting the difference between the squares of the two numbers. In this question, recognizing that the subtraction of the squares leads to a clean computation helps reinforce the concept of calculating individual squares and performing subsequent operations. The correct answer reflects this evaluation clearly and precisely.

To find the value of (7^2 - 5^2), we start by calculating each square.

First, calculate (7^2):

[

7^2 = 7 \times 7 = 49

]

Next, calculate (5^2):

[

5^2 = 5 \times 5 = 25

]

Now, subtract (5^2) from (7^2):

[

7^2 - 5^2 = 49 - 25 = 24

]

So, the result of (7^2 - 5^2) is (24). This value is obtained through straightforward arithmetic, exhibiting the difference between the squares of the two numbers.
