Which of the following expressions is true?

A. 43 • 45 < 412
B. 52 • 53 > 55
C. 32 • 34 = 32
D. 52 • 54 = 58

The correct answer is D. 52 • 54 = 58.

To find out, you can simplify the expressions as much as possible:

- 43 • 45 can be simplified to 1935
- 52 • 53 can be simplified to 2756
- 32 • 34 can be simplified to 1088
- 52 • 54 can be simplified to 2808

From here, it is clear that D is the only expression that is true.

To determine which of the following expressions is true, we can evaluate each expression and compare the results.

A. 43 • 45 < 412:
To evaluate this expression, we multiply 43 by 45:
43 • 45 = 1935
Then we compare the result to 412.
1935 < 412 is false.

B. 52 • 53 > 55:
To evaluate this expression, we multiply 52 by 53:
52 • 53 = 2756
Then we compare the result to 55.
2756 > 55 is true.

C. 32 • 34 = 32:
To evaluate this expression, we multiply 32 by 34:
32 • 34 = 1088
Then we compare the result to 32.
1088 = 32 is false.

D. 52 • 54 = 58:
To evaluate this expression, we multiply 52 by 54:
52 • 54 = 2808
Then we compare the result to 58.
2808 = 58 is false.

So, the expression that is true is B. 52 • 53 > 55.

To determine which of the following expressions is true, let's evaluate each one step-by-step:

A. 43 • 45 < 412
Multiply the numbers: 1935 < 412
This statement is false because 1935 is not less than 412.

B. 52 • 53 > 55
Multiply the numbers: 2756 > 55
This statement is true because 2756 is greater than 55.

C. 32 • 34 = 32
Multiply the numbers: 1088 = 32
This statement is false because 1088 is not equal to 32.

D. 52 • 54 = 58
Multiply the numbers: 2808 = 58
This statement is false because 2808 is not equal to 58.

Based on the evaluations, the correct statement is B. 52 • 53 > 55.
