Which of the following expressions is true?
A. 24 • 24 > 27
B. 32 • 36 = 37
C. 43 • 45 < 48
D. 52 • 53 = 56
The answer is:
A. 24 • 24 > 27
To solve, we can simplify each expression using a calculator:
A. 24 • 24 = 576 and 27 is less than 576, so 24 • 24 > 27 is true.
B. 32 • 36 = 1152, but 37 is less than 1152, so 32 • 36 = 37 is false.
C. 43 • 45 = 1935, but 48 is greater than 1935, so 43 • 45 < 48 is false.
D. 52 • 53 = 2756, but 56 is less than 2756, so 52 • 53 = 56 is false.
Therefore, the only expression that is true is A.
To determine which of the following expressions is true, let's evaluate each expression one by one:
A. 24 • 24 > 27
To evaluate this expression, we first perform the multiplication: 24 • 24 = 576.
Now we compare it to 27: 576 > 27.
Since 576 is indeed greater than 27, this expression is true.
B. 32 • 36 = 37
To evaluate this expression, we perform the multiplication: 32 • 36 = 1152.
Now we compare it to 37: 1152 =/= 37.
Since 1152 is not equal to 37, this expression is false.
C. 43 • 45 < 48
To evaluate this expression, we perform the multiplication: 43 • 45 = 1935.
Now we compare it to 48: 1935 < 48.
Since 1935 is not less than 48, this expression is false.
D. 52 • 53 = 56
To evaluate this expression, we perform the multiplication: 52 • 53 = 2756.
Now we compare it to 56: 2756 =/= 56.
Since 2756 is not equal to 56, this expression is false.
Based on the evaluations, the expression A. 24 • 24 > 27 is the only true expression.
