Final answer:
The expression |4-3i| is equivalent to 5. The correct answer is option (d).
Step-by-step explanation:
The expression |4-3i| is equivalent to the absolute value of the complex number 4-3i.
The absolute value of a complex number is its distance from the origin in the complex plane.
To find the absolute value of 4-3i, we use the formula √(a² + b²), where 'a' is the real part and 'b' is the imaginary part.
For 4-3i, a = 4 and b = -3.
Using the formula, we get √(4² + (-3)²) = √(16 + 9) = √25 = 5.
Therefore, the expression |4-3i| is equivalent to 5.
