Indicate which of the following sentences are statements. (Select all that apply.) (A) 256 = 27 1,024 is the smallest four-digit number that is a perfect square. (B) x = 27 (C) He is a mathematics major.

The answer is A and the option B = 1,024 is the smallest ... (I see its an option too)

Step-by-step explanation:

A statement is a proposition which we can determine if its true or false. An easy way that we can know if the statement is correctly written is if we can establish a mathematical proof with the info given or decide with no margin or possibility of error.

Option A can be easily determined as not true only from the mathematical expression by definition

Option 1024 IS the smallest four ... may also be determined as true or false by estimating the real roots of four digit numbers.

X = 27 is can not be proven and given a true false determination as its a random assignation of the value of a variable as well as he

Option C is not a mathematical statement but is a normal statement because can be determined if true or wrong.
