Final answer:
In the equation x^3 = 3,375, x is found by taking the cube root of 3,375, which results in x = 15.
Step-by-step explanation:
The student's question relates to finding the value of x in the equation x3 = 3,375. To solve this, we must find a number that, when cubed, equals 3,375. Through either estimation or the use of a calculator, we can determine the cube root of 3,375.
The calculation is as follows: ∛3,375 = 15, because 153 = 15 × 15 × 15
= 3,375.
Therefore, the correct answer is A. 15.
