Answer 2

It looks like you've provided a mathematical expression that includes various operations and numbers. Let's break down the expression step by step:

1. (48.34):51: This is not a common mathematical notation. If ":" represents a division operation, then this could be interpreted as $\frac{48.34}{51}$.

2. (54.38):57: Similar to the previous part, if ":" is division, then this could be $\frac{54.38}{57}$.

3. (32² - 31²)²: Here, $32²$ means $32$ raised to the power of $2$, and $31²$ means $31$ raised to the power of $2$. So, this part becomes $(32^2 - 31^2)^2$, which is $(1024 - 961)^2 = 63^2 = 3969$.

4. 22: This is just the number $22$.

5. (28×21): This is the product of $28$ and $21$, which is $588$.

6. -11: This is the number $-11$.

Now, let's put all these parts together and calculate the expression:

$\frac{48.34}{51} + \frac{54.38}{57} + 3969 + 588 - 11$

Calculating the division terms:

$\frac{48.34}{51} \approx 0.947$ $\frac{54.38}{57} \approx 0.953$

Now summing up all the parts:

$0.947 + 0.953 + 3969 + 588 - 11 \approx 4557.9$

So, the approximate value of the given expression is $4557.9$.
